Wanting to check in with guys that have had this leveling kit on for a while now and see if anyone is having similar issues. I've had my 2" RC on for probably 50k+ miles now along with some Falken WildPeak AT4's (295/60/20) and I'm getting really bad tramlining on uneven surfaces. I've taken the truck to multiple shops to have alignment checked and each one puts it in spec and states no signs of front end mechanical issues. I've lifted each wheel and checked for play in the tire rocking the top and bottom and front and rear and don't feel anything out of normal. I've pried under the tire to look for ball joint failure and I'm not really seeing anything there but I do see spring/strut compression. It rides rough as all get out, even the slightest bump like a road divider marker can easily be felt shaking the truck.

I'm wondering if worn shocks are causing the tramlining. Only thing I can really think is the shocks are worn causing it to sort of body roll on the uneven surfaces or maybe these AT4's have stiffened so much with mileage that that's what's causing it.

Or I'm reading the EPAS system may need to be reset/recalibrated?

Anyone had similar issues or have ideas on where to start throwing money first?

 

I have had my Bilstein front shock level on for over a year with no issues.

 

I do not doubt this. I've had the RC's on for nearly 3 years and this hasn't been an issue until as of late.

 

Did you just install those tires or have they been on the truck all along?

If just newly mounted they are probably the cause.

I had a car that tramlined after a tire switch, same size, different brand. Nothing fixed it except staying out of the groove on the stretches of road where I noticed it.

 

Negative I have almost 50k on them but the walk has gotten worse and worse with time.

 

Have you checked toe-in? Altering the suspension geometry with a lift (or lowering) can lead to bumpster. Bumpster is when the movement of the tire up or down causes the toe-in to change. Tramlining is often caused when a wide tire rides up a little on the side of a rut. If that rise introduces toe-out instead of toe-in, the result is tramlining. You might need to re-adjust toe-in if it is out-of-spec or increase it just slightly.

It is a very common issue to deal with in Fox body and SN95 Mustangs which utilize a modified McPhearson strut suspension and have been lowered. My 2001 SVT Cobra tramlined like crazy after lowering it until I installed a bumpsteer kit and made the needed adjustments.

Since there are few complaints of tramlining with the F150, even with a lift, I'm not aware of annyone oftering a bumpsteer kit, and assume the issue can be dealt with by adjusting toe-in. Tire characteristics, including air pressure, can effect tramlining.

 

I'll have to look at my last alignment from a couple weeks ago. Definitely something to look into. No bump-steer kits for F150, I read another post on here a couple weeks ago about the same issue and the basic gist they got to was there is nothing for these trucks.
