Many of our customers in both the GM and Ford segments of our operation, have ride height issues after lowering their vehicles.
Some very common complaints after lowering vehicles are:
-Car did not drop much in the rear
-Car is sitting lop sided
-Car is making noise now
-Car feels very unstable and floaty
-After lowering the car, some of the bushings have worn out
Many times, it is simply due to not loosening all of the suspension pivot point bolts, and re-torquing them to their specific TQ values when the car is sitting on all (4) wheels/tires - loaded.
The best way to perform this is get the car on a drive on lift, or blocks or drive on ramps.
The car needs to be level and sitting on all 4.
Loosen all of the suspension pivot point bolts enough to where there is no load on the nuts.
After ALL of them are loose, go ahead and RE-torque them all to OEM specified values.
The pivot points that need to be "indexed" or "clocked" or "timed" are any of the suspension mounting points that have a rubber bushing, as pictured below.
FRONT (where there is rubber)
***TQ Values are 81ft/lbs for all of the trailing and upper control arm***
***TQ Value for the camber adjustment eccentric bolt on the LCA (bottom pic) is 111ftlbs***
REAR (where there is rubber)
Hope this helps! Happy Modding!
