Default Truck guys...my truck is leaning to one side

Strange.....I have a 2003 Chevy Silverado 1500 (hold the jokes Ford guys). In the last year I have been noticing the driver side of the bed is lower than the passenger side.

I took a measurement and the driver side is 1" lower than the passenger side. Only in the back. The gas tank is on that side but I see it lower even when its empty. Aside from the obvious.....a weak leaf spring, is there anything else that is could be? Bad shocks maybe?

I was just going to get a set of air shocks and instal them so I can pump them up separatly, this way I can give the low side more hight.

LOL.....normally in these cases when there is something wrong with my truck I just go get a new one. But this one will be paid off in Febuary 09 and it has never given me a lick of trouble so I'm keeping it.

Never been in an accident? If it were mine I'd throw it on a frame machine first, check the measurments then on to the suspension. Is it just the bed or the whole truck, drivers side? Where did you take your measurements? Anything less than a perfect horizontal datum plane will result in bad measurements. The frame set up and measure will isolate the suspension (it should be hanging during the measurements). Find a local bodyshop with a laser measurement system.

I had a truck do that once on a 97 Chevy, I ended up putting add-a leafs in the rear and a leveling kit on the front.

Get a REAL truck......GET A DODGE! ......hey I'm not a Ford guy so I figured I'd say it.

Is GM leaf spring? For some reason I thought they were coil. Either way, it's good that you said it was only the box that is leaning, otherwise I'd say go on a diet fatso.

Nah it won't be the shocks, the shocks only dampen the ride.
If your truck does have leafs, I'd say you have either a broken leaf or the leaves on that side of the truck are fatigued. Either way why don't you run the truck into a spring shop, they should be able to tell you what's the problem within 60 seconds.

I certainly won't be using helper shocks to correct the problem.

edit:

does the box bounce around when you're on rough roads? Maybe it's something as simple as the box mount(s) (rubber block) has dried up and fallen off.
Oh, a spring shop will be able to measure things up for you (generally at no cost) "if" they are not able to spot the problem right up.

GMs are leaf springs, the Avalanche is coil in the rear with IFS up front.

Tell the fat chick to sit on the other side!

I don't know what the problem is but adding air shocks isn't the answer. You're just covering up the symptom, not curing the problem.

Check the mounting bushings for the bed and the cab, maybe one let loose. I had that happen on a GMC PU I had years ago. Granted it was a '57 so it was older than I was but I guess it could happen on a newer truck.

double check your measurements making sure you are absolutely on a level surface.

This symptom is not that uncommon on some pickup trucks. you have the fuel tank and driver on that side, probably battery too. It is likely not a real problem to worry about, however, I would have the leaf spring checked to make sure it does not have an issue. This is a real common issue with older toyota tacomas.

Measure from the frame to the ground on a level surface on both/oppisite sides, if it is not even then i would say it is a bad/weak or broken spring or spring mount. First thing i would look for is a broke leaf. If the frame measures the same side ot side then check the body mounts to see if one is rotted or otherwise not where it should be. I would address the problem not work around it with air shocks.

As far as I can tell from reading between the lines, if you don't own a Ford you are good to go!

edit:
Buy a Dodge!

















































........what, we haven't had a good truck bashing in a long while.

Rubber bushing between the bed and frame compromised.
This was my thought as well. I do put a lot of weight in the bed very often. The truck has never been in an accident as far as I know. The truck is a 2003 and I got it in early 2004 as a lease return. I did a carfax on the truck and it came up clean, thats not to say it wasn't fixed by a shop that didn't report it. But like I said I just noticed it early this year.

The lean isn't even that noticable. I bet 99% of the people driving behind me would never even spot it, but I have a sharp eye when it comes to things like that.

My measurement was from the edge of the fenderwell to the top of the tire on a level surface. I'll climb under and measure between the frame and axle. The leaf springs and all the shackels seem to be in tact and not cracked.

Oh.....and I have had a couple of Dodges and a Ford, for a 1500 size truck I'll take a Chevy anyday. If I were to go to a 2500 (250) or bigger then I would get a Ford Diesel.

Of course you would, if you like ugly 1/2 ton trucks with wimpy beds.

Just got under the truck. The bed it bolted directly to the frame at all points, no rubber bushings. And the distance between the axle and frame is 1" closer on the driver side, the same measurement I got from the tire to the fenderwell.

Everything it in tact and tight, it just seems like one leaf spring is slightly weaker.

One other thing to check is sway-bar bushings. My truck was leaning to the right a bunch, thought springs or shocks, changed 4 bad bushings and the truck straightened up.

The only reason the bed is wimpy is because thats where I make your old lady ride when I pick her up.

Your frame is twisting from the torque. When I was a kid, I had a Ranger 4x4 that had a 302 Mustang engine shoe-horned in it. I put a level across the bed at the tailgate one day and there was 6 inches difference!
