OK, so this one is not really a big deal to anyone else but me, but it bugs the crap out of me.

I came out of the mall the other day with my wife and noticed that my truck was leaning on the driver's side slightly. So I took it in to my local Meineke today to get checked out. Before I brought it in, they said it might be a torsion bar... turns out, of course, that my 2001 doesn't have a torsion bar. It just has coil springs. After they realized this, they measured it with a tape measure, from the bottom of the hoist to front wheel wells. Sure enough, the driver's side is approximately half an inch lower than the passenger side.

They said they didn't know, and pretty much just acted like it was no big deal at that point. Like I should just live with it. They did say that it might be the coil springs, but I'd be looking at a bit of $$$ to replace them, and they said that might not solve the problem.

But its bugging the crap out of me!

So I went down to O'Reillys, who've always been helpful, and two of the assistant managers happened to be manning the counter. I asked them what they thought, and they said it might be a coil spring, as they sometimes break down low (where they sit in the spring's "holder") where you can't really see the break, but because a small part broke off, it will sit lower on that side.

They also said that if the coil springs are weak, it might be the track bar. They said to test the track bar, you jack up the front of the truck to where there is no weight on it, and try to move it. If it wiggles, gives, or etc., then its probably bad and needs to be replaced. So I jacked it up right there in their parking lot, grabbed onto the track bar, and it doesn't budge at all. So I believe thats out.

I went out with a tape measure when I got it back to my apartment, and the back is off slightly worse than the front. I measured from the bottom of the back wheel to the top of the rear wheel well, and the driver's side is 3/4" lower than the passenger. I even double checked Meineke's front measurement, and yep, they were right, 1/2" off.

So I measured the coil springs, from top holder to bottom holder. Exactly the same. I'm guessing that means there's probably nothing wrong with those then?

To make sure it wasn't the weight of the full gas tank (which is on driver's side of course), I measured from the frame next to it down to the ground, and then went around to the other side and measured that, frame to ground. The same.

So it seems that the frame and suspension are level, but the body is not. Am I losing my marbles here? What could be causing this? What should I check next?

Thank you guys in advance for any help...

idk what the problem is but mine does the same thing, i thought it was just my heavy speaker box i use to have in the bed of the truck, when i took it out it didnt change ne thing, figured i just let u know u werent the only one with this problem

You said the suspension is level. Did you check your body mounts? They collapse from time to time.

I am still learning here. Where would these mounts be located at so I can check them out? Will it be obvious if one is bad or not, that I can tell with a simple visual inspection, or not so much?

Thanks Viper37!

u have and extended cab, there will be8 body mounts. two beside the rad( one each side) and three down each side of the body. just look under the cab onn the outside of the frame and it will be obvious, theres a bolt in the center of them going up into the floor. and looks like u have a reg box. theres six . two near the cab (each side again.) and four near the rear of the box more so near the bumper/.

So what is exactly ment by they collapse, are they just bolts into the cab or are they acutal mounts?

Yeah, sounds more like worn body mounts. If your suspension is all sitting level but the body is not, that's pretty much it. If the suspension was off, then you've got different parts to look at.

MIx in a salad every once in a while.

Just messing with you, Jason.

Exactly. They look like little doughnuts. Check the metal around them as well. You may have some corrosin starting due to the salty roads, which caused the steel to rust through.

Yep, regular 6.5' foot box, and quad/ext cab. Thank you guys! Will be looking at the body mounts today. If I find out they're bad, I'm assuming I will need to take these to a body shop to get fixed, no?

Thanks again!
