Hey everyone,

I just replaced the front struts and rear shocks and quad shocks. I went with Monroe oe spec struts and shocks. Quad shocks are Gabriel. I also installed new tires.

I just took it for its first drive and it drove very well. Definitely an improvement. Then I noticed that the rear driver's side sits above 1/2" lower than the rear passenger side.

I know this is a common problem. The car has stock springs and the lower isolator on the driver's side looks broke. Think this could be the problem?

It's a 90 7 up convertible with 36k original miles, but it looks like it lived a rough life.


PS: For all I know it was already like this before the suspension work.

The shocks will not be the reason for the car sitting crooked....
If its not from damage, its probably a worn spring.. or your isolator...
Most cars have a driver only for most of its life, so the drivers side will be the side to sit lower, power window will be the side to go bad, etc...
I like your car...

#1 IIRC 7up models, just like the other 90's models, got drum rear brakes (I could be wrong but????) Not that this is a bad thing And is that spring oriented correctly?
Did you pump the rear shocks before installing them or are they gas charged? Some new shocks need to be pumped a few times to get the shock fluid in the right places, not all though.

This can have a slight effect on ride height to it may be worth checking. The pigtails on the bottom of the rear springs should both be at the 9:00 when looking at the back of the car so pointing to the driver side wheel.

A previous owner installed rear disc brakes. Maybe springs installed bad from the factory? They are stock. I did pump the shocks 3-4 times before installing.

Was the car like this before you swapped the dampers?

I just helped a buddy of mine with this the other day. Loosen all of the suspension bolts and let the car sit at level and then retighten the bolts with the suspension loaded. This is just to make sure none of the bolts were tightened with the suspension hanging allowing a bushing to be twisted and holding the suspension up in that point. His was also in the rear and it fixed the problem. Just something to check.

I believe so. I never looked very close. But looking at old pictures it looks lower on rear driver's side.
