I have a 3.5" lift on my JKU. Both the front and rear axle are 1/4" to the driver side. I have an adjustable front track bar that I can use to correct the 1/8", but i dont have a rear adjustable track bar. Is it worth it to spend the money on a rear track bar just to move the rear axle over 1/8"? I dont have any death wobble or drive-ability issues, so im just not sure what to do. Thoughts appreciated. Thanks.

 

I'd definitely correct the front. In the rear you currently have a raised TB bracket on the axle right? Correcting the angle of the rear TB after the lift is more important than centering that axle dead nuts. If you had an adjustable rear TB, sure, but the rear TB itself does not see the same sort of stress the front one does. If it makes you feel any better, I have to intentionally cheat my rear axle a bit to the driver's side due to rear driveshaft clearance with gas skid plate.

 

In the rear I have a track bar drop bracket that is connected to the frame mount. So you think it would be ok to have the front centered and the rear off a 1/4" The alignment relationship of the front track bar and drag link are pretty darn equal.

 

^ I do the same as resharp. My rear u-joint rubbed the gas tank skid like crazy (aftermarket skid), so I originally trimmed a portion of the skid. Still made contact at droop, so now my rear axle is slightly shifted to driver side. My cut fenders make it extremely difficult to tell. So unless it's really bothering you, I wouldn't worry about it.

I would definitely spend the money on an axle mounted bracket to raise the rear track bar. You will notice an improvement in handling. Ditch the frame mounted drop bracket. You want to raise your roll center, not lower it.

Your front looks completely stock, so your angles are fine. Just remember: raised front track bar bracket means you have to flip your drag link. Your rear axle being 1/4" off won't affect anything.

 

+1. Almost all of us would tell you that raising the axle side TB mount is better than lowering the frame side mount. Although it might seem like the net result is the same, keeping the TB as high as possible is going to improve the roll center. Is this the 3.5" Rough Country lift? I wouldn't sweat the rear being off a bit, but, an adjustable rear TB isn't that much money if you want it dead center.

 

Yes, in the pic that is the stock TB. I purchased a heavy duty front TB to correct any flex in the stock one, just haven't installed it yet. This is why i question if is it worth to buy a rear TB at this time.

 

Thank you.
Its a Rubicon Express 3.5" lift

 

i've helped someone install a RE 3.5" lift before....thought they used a raised bracket rather than dropping the frame side. oh well, nbd. I know all these little things add up and hit the wallet. This isn't something that is going to make the jeep undriveable or anything. Might just keep it in mind for futures tweaks. It is more optimal to raise axle side, but you're not going to jump in the jeep and say "oh y, I totally feel this difference".

 

it might be a raised mount, i'm not sure now, ill have to go out and check later. So, i'm assuming the consensus is to completely center the front axle. And when i get some extra money get an axle mount raised TB relocation bracket, or just git ride of the bracket entirely and get an adjustable rear TB.

 

Even if you get an adjustable rear TB, you'll want to raise that axle side mount (assuming you remove the lowered frame-side mount). Again, the flatter you can keep the bar, and higher, the better it will be. If you just use an adjustable bar with no raised mount, it will be running at a pretty steep angle from frame down to axle..
