Greetings All, I've got a 2012 JK that's been pulling slightly left since the day I got it new from the dealer. I had the dealer check it out shortly after I bought it and they could not find anything wrong (what a surprise). It was never that bad but after a year and a half, it's annoying enough that I want to finally get it right.
My JK has a dealer installed 2" budget boost (I think its AEV) along with AEV Pintlers and 34" Nitto Trail Grapplers.
The pull to the left is mainly noticeable at highway speed. Also, I don't think it's my imagination but I'd swear it's worse when the temp outside is colder. Tire pressure is equal all around at approx. 31lbs. I've also swapped left and right tires with no change.
I found the front axle was off by an inch over to the driver side probably due to the lift but still using the stock track bar. I read that only 2" inch lift should not cause the need to replace with an adj TB but decided to go ahead and install a JKS adj TB recently hoping it would stop the pull. It improved handling slightly but it still pulls left.
I took it over to a local alignment shop knowing they can't do much except adj the toe. I just wanted the readings to see if it might give me a clue for what the problem might be.
The readings for the rear were all well within spec. The front camber on both sides is fine too. Caster seems way too low compared to spec. It's only +2.4 but at least it is equal on both sides. Seems that would only cause it to be less in a hurry to return to center, maybe a little looser steering feel, but not cause a pull. I'm not sure and would appreciate input to see if it is really worth spending money for adj LCAs. I've also read about AEV's brackets that lower the front UCAs and LCAs. I'm thinking about getting those, but they aren't recommended for only a 2" lift. Considering how low my caster is now, maybe they would be ok?
The toe settings are what really seem strange and the alignment tech even said "your wheels are pointing right but its pulling left." Left toe is +.46 and right is -.42. So total toe is +.04 which is a little low compared to spec, but I'm concerned that each wheel is so far off. Could this cause a pull to the left?
Also, I've read that some aftermarket steering stabilizers can cause a pull, but mine is still stock. I may pull it off anyway just to see if it makes a difference.
Appreciate any input regarding what adjustments I should make, or what parts I should be considering. Thanks
