Need some helpful hints on installing ball joints.
Got Napa lower ball joints, the giant c clamp from autozone...
Got the old one out easy enough.. this new one will NOT go in, with my 10 ton press or the loaner tool. I already ground down one of autozone's vice collars so it'd fit somewhat flush on the top side of the control arm.
The napa part is 0.010" bigger than the one I removed, and about 0.020" bigger than the hole in the control arm.
I'm gonna order moog from rockauto.com... assuming these napa ones arent already moog. Look familar to anyone?
Has "88" stamped in one end. The other has some nonsense markings on it. Boxes say made in u.s.a.... instructions are english/french/span and the grammer is fine, so they're not chinese parts.

Use the press if you have one. I never could get mine in with the tool. Took my uppers and lower arms off and took them to a brake shop to press the new ones in. Guy did it for $40 for all 4 ball joints.
The lower control arms only take about 5-10 minutes to remove. Two bolts with nuts on the frame, the sway bar, shock mount, and that's it.

Always more to it. Gotta move the truck out of the garage to get to the work bench and press... and there's no other place to park the truck for several blocks at this hour.
Damn.. I like the idea of bringing it to someone else. Guess I'm not racing tomorrow.
I had no other choice. Don't own a press (on the shopping list one of these days) so had to farm out that part. I know a good mom and pop brake shop that's reasonable and does good work. I took them the arms in the morning, picked them up on my lunch break, and had the car back together an hour after work.
Wouldn't hurt to align the car when you're done, even if you're not touching the uppers. Anything you do changes the steering geometry, if only slightly.
Hey Buddy,
I have always heard the new Ball joints are always a wee-bit larger,seems to take up any slack the old one caused.
When this is the case,the press is always needed.Hope it works out for ya.When I worked at a GM dealer,we always replaced the entire control arm,never the ball joint itself.Yeah they made more money off it but we never had to use a press to simply replace the joints.That being said,over the years,when I have seen ball joints replaced,it was usually done on a press.No C clamp can give ya the hydraulic push youre looking to get!

I've put some force on that press before... watched it flex 1/2". That's got some FAT steel gussets on it too. Bet I exceeded it's 20 ton rating. Would not want to witness that thing break.
Unfortunately the arbor plates are uneven thickness so sometimes it shoots parts out sideways. fkn harbor freight...
Ok, I'm gonna go find parking for my freshly waxed washed truck under a sap tree on the 4 lane bumper car parallel parking boulevard.

This ain't happening. Got the press maxed out... bj is dead nuts on center... actually 0.025" too big. That's a fifth of an eigth of an inch!
Local shop would probably just f*** the control arm or break it. I guess I'm off to the store to see if the cheapy balljoints are smaller. F*** this car pisses me off.

Who makes Napa's house brand? Any chance they sold you the wrong ball joint? I don't remember mine being THAT far off. I used Moog, bought them from CarQuest. It was definitely an interference fit, but .025 is a big difference.
That sucks man. My PST ones went in fine with a press. No way should it take that much force and still not go in. And I though NAPA was supposed to be good chit. I'd be pissed too. Would make me want to set something on fire.
I had the same problem, replaced my ball joints 2 months ago. New ones looked just like yours and were too big. It said Acdelco in the box. I didn't take them to shop for press, because I thought it would not fit and the aluminium would just break under the pressure. Didn't have time to investigate why they were so much bigger and order new parts, so I grinded the extra material off from the joints and after that it was a piece of cake to get em fitted.
I'd say there are probably lots of "faulty" ball joints out there.
Done this twice now with the same issue. One set from PST and another set my friend bought, but don't know where.
Fortunately for me a Corvette buddy has a full size lathe in his garage and we took the ball joints down to .010 over. Plus this makes them perfectly round and very smooth.
I also had a problem with the C Clamp tool we borrowed from Auto Zone. The piece that was supposed to drive in the ball joint would not match up well and the joint kept going crooked. We finally machined an aluminum adapter that fit the ball joint perfectly and then everything went in just fine.
Also had to take a die grinder to the arm to make room for the cylinder piece of the C Clamp so it would sit flat and centered on the opening.
Guess thats what you get when you don't use the official GM tool and go generic.
I know everyone can't do this but I am not willing to force a part that is .030 too large into an aluminum piece. I don't have a press that strong and don't want to risk cracking the arm.
Guess everyone needs to just be aware of this issue and budget for a machine shop to insert the bottom ball joints. But measure first. Yours might fit just fine.

I bought Moog ball joints for upper on my 93 Dodge Dakota and one fit fine and the other was too small and just spun in the arm. This thing was in a Moog box.. Went and got one from Napa and it worked fine. Don't know what the deal is, but seems like Moog may have a quality issue. Part numbers on the boxes were the same.
I used NAPA on my truck - Hammered them in and they never failed - the tool wasn't worth a crap - doubt that you'd want to try that on your Vette - there is a suspension shop around the block from NAPA's Convoy's warehouse and NAPA has a machine shop so you could ask them to do it. I think they quoted me $20 or so to press them on, so if the A-arms are off, you might want to fork out a few more Bucks to get it done and your Vette back together.
Some of you may find this of use. It was in HOTROD or CarCraft about 20 years ago. I hope they don't mind. At least they're getting a plug for their mags.
I finally got around to building it about four years ago. It cost me about $45 for the steel, plus the bolts and a bottle jack that I already had and can still use.
I made a few changes to it and it works great. Larger piece of steel above the jack ram; 3/4" steel instead of the aluminum on the cross bar, with the push ram attached directly to it; 3 1/2" spacing on the verticals so I can use four pins if needed. I didn't use bolts on the table. I welded it up with four, 5/8" pins and tubing spacers for more stability. I made it 5' tall instead of 6' and I can still put a car axle in it.
If anyone should want to make this, buy the pieces cut like the article says and get a couple of extra pieces for support and spacers. The ones that come with the Harbor Freight press are cast steel and will snap.

I don't want a shop to put em in and break the arm. I'd have a shop machine them down if anything, but I'd rather try a different brand ball joint first.
I'm trying to identify, either by brand or type, which ones fit and which ones dont. Nobody seems to remember what brand they purchased.
I used to have occasion to wander around in the local NAPA central
warehouse back in the mid-90's.
At that time, in Canada, they stocked MOOG in MOOG packaging. If
you call and get someone on the desk with experience in the warehouse
they may be able to say whether this is still the case. Alternatively,
they could tell you whether they have the MOOG catalog, a possible
tip-off. Assuming they still use paper instead of 0x1's in your part of
the world
A last thought - in these parts, customers can handle parts and resellers
can return stock.
So it is not outside the realm of possibility that your parts were handled
and returned to the wrong boxes. A parts-person ought to be willing
to pull more 260-1338's to do a visual or to measure those for
comparison to what you received.
BTW - while I do not have direct knowledge of BJ fitment, from other
experience, I side with those who state that an 0.025-0.030" interference
fit is asking for trouble.
