Review: Worked great on my 2006 Chevy Trailblazer SS lower front ball joints! - I purchased the Astro Pneumatic 7897 Ball Joint Service Tool and Master Adapter Set as an desertcart Warehouse deal after *way* too much painful research on trying to determine what ball joint kit would work on my 2006 Chevrolet Trailblazer SS front lower ball joints. Way too many of these reviews say NOTHING about what vehicle they used it for - shame on them. I emailed Astro and a few other companies about their application charts (specifically whether it would fit my vehicle) and almost every reply and every chart is close to useless. Only OTC responded with an affirmative via an application chart, but they required an additional $77 purchase for 4 more receiver/press pieces! OTC and Astro both listed length, ID and OD sizes for all their pieces though, so I was able to sort out that this Astro kit *might* do the trick. Fortunately, I was right. So my first goal was reliability - many people either hate or love the C frame that whatever brand kit comes with. So I weighted reviews on that topic. The confusing part about that is so many of these C frames (and kits) are identical, sold under different names, and sourced from China (well, all are sourced from China). Second goal was finding the right size receivers/adapters. That was almost impossible, since only OTC listed my car and virtually no one would list their application in their reviews (what is your problem, reviewers???). Through my frequent forum travels, I knew the Powerbuilt/Alltrade 648617 Kit #46 would fit - that's what most Autozones rent. But except for a deal I let slip through, it seemed like the price recently went up a bit and those were around $200. Third goal was affordability, since I was going to use this once for my TBSS, and *maybe* again on our Lexus RX330, but less likely. I could use the press for other things, like bushings and bearings, I suppose, but still - fairly limited use. Thanks to the desertcart Warehouse deal I got it for $93 in Very Good - Used condition. As usual, I made out on that deal, because it looked brand new. I can guarantee the C frame and threaded rod were NEVER used - they had some shipping/plastic grit on them that couldn't have been on it if it were used. And of course, the most important thing - did it work? Absolutely. The lower ball joints on a GMT360 (Trailblazer/Envoy/Ascender/Rainier/Bravada/9-7x) are notoriously nasty to remove, thanks to a horrible method GM uses with a flared end opposite the stud side with 3 tabs that are even more flared. I actually bought new lower control arms and bought new Raybestos Pro Grade ball joints and removed the cheap ones from the new control arm and put the Raybestos ones in. Why? Because after buying every front end part (inner/outer tie rods, stabilizer links, control arms, bushings, ball joints) for my truck 2 and 3 times over now in the past months, I've found about 33% of the time you get counterfeit or wrong parts. I gave up getting real Raybestos Pro Grade Lower Control Arms and decided to make my own, so to speak, replacing ball joints and bushings with ones I purchased seperately in 2 new lower control arms that kept showing up no matter who I bought it from. Why not just replace the ones in the arms of my truck? This way I had more time to make sure I could press these things in and out and also much less downtime with my truck. Anyway, I digress - the press works. I had to spray down the joints with PB Blaster, hammer the flared tabs and sides in a bit with a chisel and punch so they stuck up from the control arm, and then I used an angle grinder to grind that flared part off as much as I could without damaging the control arm, including a little finish work with a Dremel. One I let soak overnight, but after getting it out I didn't even let the other soak more than 10 minutes. I did use an impact wrench (an electric one from Harbor Freight - the cheap one, around $35 on sale), althought I tried to do it manually with a 25 inch breaker bar just to see how hard it was, and it was HARD - I was pretty sure I was going to snap something. so I went back to the impact wrench. I just kept pulling the trigger in 3-5 second bursts on the impact wrench - it made slow progress but it did make progress, and after 15 or 20 seconds it made a loud pop, and then a few more trigger pulls it came out the rest of the way. One note, I made sure the threaded rod and C frame threads were clean and in good shape and oiled them repeatedly during use. Far too many people don't use enough oil for these sorts of things and then complain. So while the kit itself didn't list my truck (or much of anything, actually), it worked, it worked well - I saw no visible bending or damaged threads - the rod didn't slip, everything felt like it was of reasonable quality and finish (these aren't SnapOn sockets, mind you) and I'm very happy I bought the kit. Would I buy this if I was a suspension shop? Maybe not - but for the casual consumer - I highly recommend it. Review: Beats the autoparts rentals everytime. - I bought this to replace the lower ball joints on my 2003 Trailblazer and this was the perfect kit. When I did the two upper ball joints I rented a press from the auto parts store and both times the press kit was missing parts, and wouldn't you know it, they were the parts that I needed. Bent forcing screws, spread out C clamps, deformed receiving cups, just a bad experience every time. When I found my lower ball joints to be bad, I started looking for a press kit to buy. I started watching YouTube videos and found Eric O. from South Main Auto talking about this kit and after a few more videos decided that this was the kit for me. Ordered it and it arrived a day later. The kit had everything that was needed, no broken latches, no broken case. I put some Mobil 1 grease on the forcing screw and went to town! My Aircat 1150 gave that forcing screw all she had, and anyone that has done the lower ball joints on a trailblazer knows that they're a bear to do because chevy presses a flange on the top of the ball joint that you have to chisel off (thank god for an air hammer). The press worked amazingly. Some folks have complained that the c-clamp is too small, but Astro makes a larger clamp as well, desertcart sells it here: https://smile.desertcart.com/Astro-Pneumatic-Tool-78100-Goliath/dp/B01JBOA4GK/ref=sr_1_1?ie=UTF8&qid=1546564530&sr=8-1&keywords=astro+78100. ## Features - Removes and replaces ball joints - New forged alloy C frame press has industry leading strength and can alone be used to remove and replace universal joints - Set includes all the receiver tubes and removing/installing adapters needed to work on press-fit upper and lower ball joints on most Domestic 2 and 4 wheel drive vehicles plus many Import and Euro applications though the 2020’s, guidance for over 1,200 applications listed in the manual. - Also included is the #2030-1 live center forcing screw plug - Astro’s famous forged alloy press measures 6” internally, 8.75” overall.

In my opinion, if you can sneak it past your wife. Get this kit. Then go buy the $129 12 ton press at harbor freight. **Q: 7897 ball joint press. will it work on a 2003 chevy silverado 1500 4x4?** A: it should. i used it on a 2004 f150 lightning and had no problems and it does have the extensions included for all types of 4x4s. hope this helps **Q: Will this work for lower ball joints on a 2000 ford crown victoria?** A: as long as it's the pressed in type ball joint, Yes. **Q: Does the master set have the angled cup for jeep ball joints?** A: I can't say.

I was hesitant to purchase this kit because of it being manufactured in China. I wanted either a made in usa one like the otc, or a made in Taiwan one like the powerbuilt. I debated and researched for days, watching video after video, review after review. I literally could not find anyone saying bad things about this kit, including tons of automotive mechanic channels on youtube. A well known channel, Eric O from South Main Auto has run this kit often, and in dozens of videos in the rust belt state of New York. I've never seen a cup warp, the c-clamp bend, or the forcing screw break, or strip. I've also used this kit a dozen times myself over the last year, and I have never had so much as a glitch with this kit. I don't know why everyone is so stuck on the made in usa otc 7249 kit. I actually reached out to otc customer service and they told me that only the clamp itself is made in the US, and nothing else. The forcing screw, the kit's adapters, and the case are all still made in china!! Message them and ask if you don't believe me. I know your going to say, " well the US made one is better forged metal," but I'm telling you it's not. Otc actually used to manufacture the 7249 c-clamp in China for many years before manufacturing was moved to the US, and they actually still manufacture many of their other kit's adapters, attachments, forcing screws, and clamps there as well. In fact, otc still manufactures several other versions of their c-clamp in China as well. The c-clamp in the otc 6530, 6559, ca6630, 8031, and several others are all still manufactured in China. This astro kit is just as good, or better than the otc kit, I'm telling you. The astro clamp actually weighs 2 lbs more than the otc clamp, no joke. Tons of companies including snap on, matco, Mac tools, vim, bluepoint, Williams, and others all have stuff manufactured in China. Although most tools that are manufactured in China can definitely be terrible quality, not everything is going to be garbage. This kit is a testament to that and I don't regret my purchase whatsoever!! ## Frequently Bought Together - Astro Pneumatic Tool 7897 21Pc Ball Joint Service Tool and Master Adapter Set - Astro Pneumatic Tool 78100 Goliath Ball Joint XL C-Frame Press - Astro 78807 5-Piece Pickle Fork Ball Joint Separator Set --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/6873771-astro-pneumatic-tool-7897-21pc-ball-joint-service-tool-master](https://www.desertcart.pl/products/6873771-astro-pneumatic-tool-7897-21pc-ball-joint-service-tool-master) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-30*
