65 sitting low in rear

[Michael G.]

I just noticed that my 65 is sitting low in the rear, significantly. This was not the case before my last drive (about 40 miles). Before I put it on the lift, what am I looking for, a broken spring?
Thanks,

spring liners and outer rubber bushings could be shot.

Mike springs do support the weight of car, look at the springs and look at rubber cushions in case one dry rotted and fell out.

Re: 65 sitting low in rear

The most common cause of rear ride height loss is old, compressed spring link cushions, but since you noticed a sudden loss after one drive the spring is suspect. So take a look at the rear spring link cushions, and if they're in reasonably good shape, there might be a broken leaf in the rear spring.If you do replace the spring link cushions, buy from GM. They're still available and the p/n is in your AIM. The aftermarket cushions are junk and rapidly start cracking and compressing.Duke

Check alignment, rear squat.

Can’t see any cracking in the spring, but it has absolutely no bow with the weight on the wheels. Is that correct?

Yes.

My 63 with weight on wheels - 1/2 tank of gas and no spare tire or tub..no passenger or driver.
With a full tank and the other things mentioned weighing the suspension down the spring would be dead flat..

Are you sure the rear is sitting too low...sometimes looks can be deceiving...?

Re: 65 sitting low in rear

It doesn’t look too bad now, maybe its the full tank of gas (I alway keep it around half full) that makes it look low in the back. The top of the front tire is about 3/4 inch below the fender well, and the rear is a about a 3/4 inch above. The rocker is essentially level.

To me, the front looks like it's a little high. The rear looks about right.

Re: 65 sitting low in rear

Why don't you quit speculating and just measure the right height front and rear per specifications listed in the AIM?

Re: 65 sitting low in rear

Didn’t know it was there, thanks, no problem.

For 1965, AIM UPC 3, sheet 6 and UPC 4, sheet B5.

Re: 65 sitting low in rear

Well, it's in spec at all four locations. Spec is Front: 8.35-8.85" Rear: 8.54-9.04"

Passenger front: 8.65"
Passenger rear: 8.62"
Drivers front: 8.85"
Drivers rear: 8.70"

It must be an illusion...although the maxed out driver’s front measurement might tend to make the rear look low. Can’t believe I can see that little difference. Joe’s right, I think...
