Default How Big A Press Do I Need

I posted this question once before but did not get a responce. I plan on rebuilding the front end on my 1985 Corvette this winter. My question is will a six ton press take care of pressing in the bushings and ball joints. Harbor Freight has one for $60.00 and if it would work I would look for it on sale and buy it. Also where can I get the most detailed instruction on how to do thi job. Pictures would help!

I don't know the answer but why not get the 20 ton press and remove all doubt. That's the one I bought and It will press about anything for just a bit morer $$$.

A 6 ton press should be plenty. Fixtures are the kicker. Those "A" frames are quite delicate without the cross bar that bolts to the frame. The "A" frame bushings are NOT serviceable, according to GM, so authoritative information is not readily available. You might be better off spending the $60.00 on having a pro with the experience and tools, do the "A" frame bushings.

RACE ON!!!

Yeah, if you don't know how to set them up just right it wouldn't be hard to break them. Re/ the press, most of the bushings can be done in a vice. The only ones I've used a press to remove so far were the bat wing ones. Since I have a press at work, it was just more practical. It's a 50 ton and the dial never moved off of zero.

A press ya say?

I did both the upper and lower ball joints in my garage using the tool that I rented (for free) from AutoZone.

I did 12 bushings (polys) on the rear and only had to use my bench vise and some assorted 1/2" drive sockets.

I like free stuff.

The tricky ones, are the upper "A" frame bushings. The rest, aren't too bad. Be careful you can bend or break an "A" frame in a heatbeat.

What are these A-frames you mention? Control arms? I need to put in new bushings. I gave up when I couldn't break the first bolt loose on the rear spindle. Time to get some impact tools.

Yes, common name for the fronts, particularly when they're shaped like an "A".

YES! As Corvette Kid NC said. I've known them as "A frames" for a hundred years. I looked them up in my parts book and it calls them, "Arm, Steering Knuckle, control". The rear, on the Corvette doesn't use an "A" frame or control arm, as such. The knuckle movement is controlled by the lower camber rod and the half shaft. The tie rod in the rear is to stabilize the knuckle from rotation and prevent rear steer.
