Sub frame mounts

[cmaro1]

im about to replace the sub frame mounts in the 74 camaro, i have never done anything like it beforeand i was just wondering if thares any hints or tips or anything i should look out for? the engine and trans will be out and all the bolt on stuff eg: bonnet, gaurds and bumper will be off the car. Is it possible to replace the mounts one by one rather than compleatly seperating the subframe from the body?

Probably could do it that way, but do you actually want to undo one and keep the others tight?

You may be able to do two on one side, and then two on the other, but would probably need the opposite to what you are doing to be loose.

They sit down in the mount holes, and need extra clearance to get in and out.

I'd do them all at once, you only need to raise the body 1-2 inches

Done many Cluxford.. .. try this too..

When the frame is twisted the panels will twist.. so insulate the gaps.. open your hood and your doors.... if a panel gap where paint is close could close.. then put something in there like cardboard or thick rag.
Jack the entire car up evenly... on stands... leave the jack free.. get some wood ..like 2x1 etc..& few different lengths so you can spread the pushing up of THE BODY evenly..... crawl under and just loosen the PAIR of mounts you want to change..do TWO across per session...
Once loose.. see if the old mount will just slide out.. sometimes they are that compressed they will.. but regardless now put the jack under and a peice of wood so as to not damage the floor/body area.. and gently jack the BODY up..only needs about 10mm play most times to slip the new mount in.. .. maybe start with the mount under the seat.. the rear mount. and work across.. The center mounts at the base of the firewall are the hardest.. and you may find you'll need to loosen off the rear mounts abit to give youself some additional gap..
Bit of a slow way.. but I've done many now.. one by one.. pair by pair.... Just put the radio on.. crawl under and enjoy....

Good advise...I was going to riase the gaps issue.

No I haven't done many...just the ones on my car so far on the camaro, but have done others on some 60's and 70's pontiacs (lbeint most of those were full frame cars not sub framed)

I know the gaps do change a bit once the new mounts are in
