Thuren Adjustable Trackbar...and some Insight?
Figured I'd ask a couple questions before I tackle this project. It seems pretty straight forward, but as always, something is off nominal with my truck.
I've upgraded suspension and 3" coils in the front, T-style steering, ball joints, control arms, Readhead steering box, steering box brace, etc. Everything on the front end is tight, tracks straight with no issues, etc.
But I've had the OEM track bar on there since doing all this. The wheels are centered in the wheel wells (front to back), but as we all know when you level it shifts the axle since the angles change. This shift is normally towards the drivers side (which gives more clearance to the drivers side). Currently running 35x12.5R18 Ridge Grapplers on Mayhem Combat wheels (18x9 w/ +18mm offset).
Prior to this I was running Toyo MT's (35x12.5R17) on some no name wheels...they were running less offset (maybe even negative as they stuck a bit beyond the fender flares). With this setup I had no rub on either of the control arms.
Here's the caviat. With the current setup (Mayhem's) I have slight rub at full lock on the upper and lower control arms...on the driver's side! This in theory shouldn't be the case, but when looking from the front of the truck, my axle is shifted towards the passenger side.
Has anyone experienced this when leveling? I know every truck setup is different but in theory this shouldn't be the case. Everything is straight on the truck.
Anyway, onto the Thuren bar. Thuren recommends 39-1/8" eye to eye on his bar to center the axle...I'm assuming this is also in theory that everything follows nominal and the axle is towards the driver side and you need to lengthen over stock to re center the axle. So I would need to shorten the track bar from OEM in my case? What am I missing here? I'm not sure the Thuren track bar can shorten the amount I'd need it to for re centering purposes?
Let me know if any of you have experienced this before or any advice you have. I'll be drilling out the mounts as well for upgraded hardware, so any advice for drilling angle of attacks would be welcomed too!
