I need a little advise. Just installed 35's on my rig. Before I had 33's and did not have issues with flighty steering. What could be the cause. Do I need to set more toe in? I thought I seen somewere on the forum to have the front point in 1/8" differnence than the back of the tire. Here is the setup I am running. This weekend I am going to install the AEV drop bracket to help with front end geometry. Maybe this will help since I am not running adjustable control arms.

RC 3.5 " Series II lift
JKS front Adjustable Track Bar
BDS quick Discos
315/70/17 Firstone Destination M/T's
Stock 17' Rims
Upgraded Ball joints
Replaced All LCA bolts/Trac Bar bolts to larger size from North ridge 4 X 4
MBRP Catback Exhaust( I Know that doesnt matter, wanted to throw in for the fun of it!!)

Eveything else is stock

I truly appreciated the help since it is became an annoyance to drive since I put the 35" beef on.

 

You're already on the right path. Bumping up the castor slightly will tighten up the steering. LCA's, in my opinion, is the best option but the drop brackets should suffice with your setup.

 

What tire pressure you running?

 

I have the same lift and experienced a similiar issue. I replaced the stock trackbar with an adj one. removed the trackbar relocation bracket and used the stock pitman arm and it now drives beautifully

 

NTB put 35 lbs in the new tires. In a few days Im going to put the AEV drop brackets in and will see hows that changes things. I already have the adjustable track bar. Still running the Drop pitman and relocation bracket, will change those out if the drop brackets dont help.

 

Same prob here... Took it to 4 wheel parts and the techs recommended aftermarket lca's to allow for more adjustment. I also read that somewhere else on this site. That is what I'm gonna do to fix my steering.
