2001 Chevy Blazer LT 4X4, 179,000 miles. I just want to verify that I have bad front suspension springs. My Blazer is leaning down to the out side slightly. I have had the front shocks replaced as well most of the normal joints and bushings. The only thing I can think of is that my front driver's side spring is shot. I just had the radiator, water pump, EVAP purge valves, and a bad front bearing on the same wheel just replaced. If it is a spring it will have to wait until after the first of the year for funds. It just never ends with this thing. . .

 

Simply crank the outside bar a little tighter, which ever side the outside is.

 

Like LeWhite said, you just need to tighten the torsion bar for the saggy side. The easiest way is to jack up that side of the vehicle, then go under and tighten the torsion bar bolt. The general rule of thumb is 1 full turn = 1/4" height. You should get your allignment checked after adjusting the torsion bar height.

If you don't know where the torsion bars are, it will be a bar running beside the frame from the lower control arm to the center of the vehicle just behind the B pillar. The adjustment bolts are at the rearward end of the torsion bars.

 

To adjust front chassis ride height, the torsion bars need to be adjusted. Here are the measuring points:



The easiest way to measure them is park the vehicle on a level surface, front to rear, and side to side, (do not jack it up). Bounce the front & rear bumpers a few times so the suspension "settles". Measure from the pivot bolt to the ground. Measure from the knuckle to the ground. Subtract the knuckle measurement from the pivot bolt measurement. The answer is "front chassis ride height". Bounce the vehicle after each adjustment to the bars and measure again.

Here are the specs for 1996 & newer:

4WD (except ZR2) = 4.6” to 5.0” (4.8” is preferred)

4WD ZR2 = 4.6” to 5.2” (4.9” is preferred)
