Body Mounts & Ride Height

[Big Block Bob]

My Malibu is about 3/4" lower in rear on passenger side.
I have replaced rear springs but no change.
I am thinking body mounts (frame is good).
Are these hard to replace?
Any other suggestions on difference in ride height?

Thanks

Have you checked for spring isolators? They can account for a change that small. I'd be leary about changing body mounts... they're not too difficult (just time consuming) if the floorpans/mounts are solid, but if it's rusty I would probably leave it be. Judging from your avatar it looks like it's in pretty good shape overall. You could soak them with some penetrating oil to be safe.

That makes sense, and why would the entire left side sag almost an inch?
Hopefully an isolator, I will check that first, thanks.

If both springs are replaced I can't say for sure. If it had the original springs I would just say it's just from age (how often do you drive your car without any passengers?).

I thought it was springs because they were original, but after installing new springs ride height was same (with passenger side slightly lower). That is why I thought rear body mounts might be worn.
Hardly ever have passengers in rear seat. Not sure, either body mounts or spring isolater, can't think of anything else?

Is it 3/4" lower on the passenger side with... or without you in the driver seat?

Without anyone in the car.

When we're setting up the G-bodies (for racing), we get the car to full weight including driver, and then try and make it level. I know this is for racing and yours is most likely a street / strip car, but take it for what its worth.
