Axle swap aligning
 
I've installed a 4" x flex lift under my 2001 tj. The rear is a 8.8 already set up. The front I'm swapping in using a truss n brackets that I've built myself. The rear is all hooked up and as square to the frame as I can get it. The front is hooked up but when I meAsure from the center of the axle wheel flange to the front axle it's off. The passenger side is a quarter inch further forward than the driver. Will this be a problem? Can I adjust that out with the tiered aligning ? I really don't want to pull the front end again as I've done it 8 or 10 times now. Any of u people who have frontend alignment knowledge please give me your input.

Im not a front end guy but i'll take a stab at it.

When your say its further forward , measuring from were to were.

IMO 1/4 forward is not that big a deal,

set the toe , center wheel and done , then watch tire wear

There are some alignment techs on this forum, maybe they can chime in

Not a big deal, you should be able to adjust it with adjustable control arms?

Can you explain a little more where you are measuring from? You should pick a fixed point on the vehicle centerline to measure from

I've got adjstables but undoing them to adjust gets old. I've been measuring from the center of the bolt at frame on rear lowers. I figure that will keep the axles square to eachother. My castor is correct, can't do tie yet as I haven't built tiered yet.

A 1/4 in axle offset is kind of pushing it. There are a lot of angles to think of caster, camber, toe, toe out on turn, rear thrust angle, and more. That is not to mention the driveline geometry (drive shaft, u-joints, etc.) that should be considered, due to the axle not being square. Just because a vehicle will align does not mean that it will drive and handle properly. It could be difficult to control at speed, or it could be fine. If it were me I would probably leave it for now, complete the project enough to put it on a alignment machine and go from there. Once you are at that point and you verify that the rear end is square, you will have a more positive reference point for adjustments.

Best of luck.

Well I finally got it on the road. For all homemade brackets and a 4" lift n axle swap it doesn't handle to bad. I still need steering stabilizer and a sway bar but got it up to bout 40 n wasn't to bad. It feels squirrelly though do you think sway bar will help that or trackbar adjustment or what? I'm pleased overall and confident offroad it will be fine but I'd like to be able to drive At speed inroad as wel. Thank for the input!

For the most part she's driving. Kinda like driving on jello but overall I'm proud if the outcome. It took me 19 months but I've added tube fenders(DIY kit), 4" xflex lift ( wish like hell I'd of went longarm), waggy dana44 front with ford hubs, slip yoke kit, and 37" GY mtrs. It sat so long the clutch disc had seized to the flywheel. Had to pull tranny so went ahead n replaced noisy throw out bearing to. Now I'm saving up for front locker, planning ox unless find reason not to or great deal elsewhere. Then I stall my front 4.56s n I'm ready. Hoping to be wheeling again by January. Well I tried to post pics but can't.

Congrats man, You don't have a sway bar ? If not that's why it feels "squirrelly " IMO

jeeperdad1977 12-06-2013 07:08 PM

No swaybar or steering stabilizer. Today I started on brackets for swaybar. I'm gonna run the or bar n the links that came with my lift. I really think she'll be good after that. Ill try to post some pics.

Here's final product on frontend. The spring plates and lower arm brackets on axle are blue torch everything else I fabbed with a torch grinder and welder. Oh n the steering setup is from tuff stuff with 1 ton tierod ends and 1 1/2"x1/4" wall dom. I'm proud of it n it seems to be good so far but if I ever do another front ill def get a truss n kit.
