Hello, new guy here w/ a 78 who needs some help. I've done a lot of work recently. New front springs, front shocks, front brake calipers and brakes hoses, all new tie rod ends, idler arm and sway bar links, and I also put on new energy suspension rear leaf spring bushings. I aligned the car this weekend (well what could be aligned, read my second issue). The alignment was the worse I'd ever seen before and the car drove SO much better than before, no longer pulls, bump steer is gone, and steering wheel is straight.

First issue is the brakes. The car pulls HARD to the right when applying the brakes. I've bled the brakes and get fluid from all the bleeder valves, but it still pulls just as bad as before I replaced the leaking front calipers.

The second issue is with the rear suspension. The car sags. The left side is lower than the right side. I figured the problem was likely the worn out spring bushings, but I replaced those and adjusted the ride height. Both sides are out of adjustment and it still sits 3/4" lower on the one side.

This might be of help. Look at how badly out of alignment the rear end is:


The camber adjustment on the ride side was already pretty much maxed out so I couldn't get past -2.0 degrees, and I didn't mess with toe adjustment since it looks like you have to unbolt the rear trailing arm? Anyways I need to find out why it's out of spec and why it sits lower on the left instead of trying to correct it with an alignment.

Thanks for any suggestions,
Jesse

 

You have some seriuos issues my friend. First would be to get the brakes in proper order. You still have air in the system. My need to get them power bled. Next would be to get the car to a shop familar with vettes and get an assessment. Make sure you don't have frame issues. Will be cheaper than throwing parts at it that may not help. With the proper parts the shop will be able to get that thing dead on.

 

If you're dealing with worn out suspension bushings, particularly the trailing arms, strut rods, and a-arms, then it can be impossible to ever get the alignment sorted out. And your car is a '78. So if they're original, you can pretty much bet they're bad. You replaced some easy stuff, now it's time to dig deeper.

The sag on the LH is pretty common. You could try adjusting it out, but more than likely you need new springs front and rear.
