1) The average 80 driver is not taking his rig on the Rubicon.
2) The average 80 driver on 35s is taking his rig to the mall🤷♂️
3) I have run the rubicon many times first on 35s then on 37s and I’ve been on 39s for the last two years running a stock Schecter shaft.
4) If you run hard trails...
Ha ha but you got sucked in the the 105 upgrade anyways.
I put the blame squarely on mud :rolleyes: I have my 105 kit setting on the shelf ready to be shipped off to Redhead with my spare Box😂
If it were my truck the first thing I would do is get it on Jack stands and have someone turn the wheel while you look for issues.
You can also do the same with the wheels on the ground.
The 105 sector shaft is just stronger and won't change the steering feel.
