I just noticed this the other day and thought I was on uneven pavement, but my rear drivers side is sagging down a little bit. Hard to say how much exactly, but its noticable. Any idea's what would cause this? Bad shock?

 

the weight of gas in the gas tank.

 

LOL for real? I never thought of that....

 

My 99 Scab did the same thing, come to find out the previous owner had attempted to level the front with the rear by cranking the torsion bars. Well he had the front passenger side up higher than the drivers side causing the rear drivers side to look like it was sagging. All I had to do was lower the front passenger side a bit with the torsion bar and it leveled everything out. Hope this helps.

 

could be a broken leaf spring...most likely is...

 

Are they expensive?

 

Most likely the gas in the tank,mine does it, too. I have add-a-leaf and helper springs on the rear and leveling kit up front. I would notice it more on some days than other; after putting two and two together, the gas was the problem by process of elimination; good shocks and leafs, leveled out tb, hope it helps.

 

I adjusted the torsion bars and leveled it out.
