I have a 2011 Laramie with a rough country 2.5 leveling kit (2.5" front spacers & 1.75" rear spacers) A few months ago i noticed my front driver side wheel to fender gap was less than the passenger side. i didn't think much of it at the time since i was parked on a hill. Even on level ground i began noticing there was a difference, other people don't notice but it's just one of those things that annoys you till you fix it. Today with it sitting on level ground i took some measurements from the ground in the center of the tire to the bottom of the fender.

Front Left - 38" 13/16 (38.8125")
Front Right - 39" 3/16 (39.1875")
Rear Left - 41" 3/16 (41.1875")
Rear Right - 42" 1/2 (42.5")

So basically my driver side is sitting 3/8" (.375") lower at the front & a whole 1 5/16" (1.3125") lower at the rear. ( I did have a full fuel tank at the time but not sure how much of a difference it would make).

I'm just wondering if my coil springs are starting to get weak on the one side or if it's a shock issue. My truck only has 29,000km (18,000miles), the only other thing i can think of is that the spacers aren't the same thickness but i have a hard time believing that. Let me know what you guys think, it's starting to annoy the hell out of me.

 

i suppose the only way to diagnose this problem would be to pull the springs out, measure them and if you have to, take them to a shop that can put some kind of load/pressure test on them for ya.

 

You could try swapping the spacers from drivers side to passenger side and I think that would tell you if the spacers are the problem....

 

If you measure from the ground, you induce any difference from the tires sizes. The proper way to measure suspension, is to use the wheel as the starting point. Measure from the bottom of the rim lip to the fender. This will measure only the suspension difference.

 

Sounds like maybe a inferior spring(s) going away. (it does happen...!)
I highly doubt its a shock issue (unless they have progressive springs internally)

 

Since the biggest difference left to right is in the rear that's likely where the problem is. Make sure the coil springs and insulators are correctly orientated and seated properly. Standard shocks will not alter ride height.

 

Oh I just thought of something after blakels post. He stated to make sure the springs are seated properly. Sometimes during a re install the springs will twist when tightening the shocks and wont bottom out in the pocket of the boot. Good call blakels.

 

awesome thanks for the input, I'll check it out and see if that's the issue
