WH Wheel allignment after JBA arms & CRDSTU LIFT
 

Hey Guys,

I recently installed a set of JBA upper arms and CRDSTU Lift kit on a WH.

I took it to a suspension shop to have an alignment done.They tell me that the camber is still +0.5 deg out on the front and they cant dial the camber back to 0 even with the caster/camber maxed out.

Has anyone experienced similar? and how have you rectified the issue?

Cheers

The only camber adjustment on a WH/XH front end is from the lower control arms. Refer to the following link for info:

http://www.jeepgarage.org/f185/cambe...#/topics/29296

Can you confirm how they were trying to adjust the camber? If what they are saying is true and correct then the only other option would be adjustable upper ball joints, but I would exhaust all other avenues first.

From my understanding, they were using the bolt through the lower control arm.

I am a little confused as to why they werent able to dial it back. After all my research, I havent come across anyone who has had the issue.

The car hasn't ever been in any accident, so theres no way any of it could be bent. The bolts arent seized either.

I wonder if there is a possibility to drill the holes wider on the LCA bracket to push the arm out further.

From recent personal experience most don't know how to align these Jeeps.

I have the CRDstu lift and after they called me and said they cant adjust the camber I explained to them how to do it and they got it to Left +0.08° and Right +0.06°

Is it 0.5° + or -? Up to - 0.7° is within range.

SPECIFICATIONS
DESCRIPTION SPECIFICATION
PREFERRED CASTER 4.0° RANGE 3.55° to 4.45°
PREFERRED CAMBER -0.25° RANGE + 0.15° to - 0.70°
PREFERRED TOTAL TOE-IN + 0.25° RANGE 0° to + 0.5°
MAX Right Tyre/Left Tyre DIFFERENCE 0.5° on all 3 adjustments.

Here is a manual, I suggest printing the 5 pages on wheel alignment (under suspension) and giving it to them.

From the manual (page 37 sub section 2)
STANDARD PROCEDURE
CAMBER, CASTER AND TOE ADJUSTMENT
NOTE: SUSPENSION HEIGHT MEASUREMENT MUST BE PERFORMED BEFORE AN ALIGNMENT.
Camber and caster angle adjustments involve changing the position of the lower control arm with the slots in the
frame brackets to move the lower control arm inwards or outwards for proper adjustment. This can be achieved by
using a long pry bar with a curved tip and inserting the pry bar into the lower control arm frame brackets
and prying inwards or outwards.
NOTE: Camber and caster adjustments must be made at the lower control arm Do not use the upper control
arm for Camber and Caster adjustments.
NOTE: When the lower control arm pivot bolts are loosened the lower control arm will normally go outwards
automatically with the weight of the vehicle.

CASTER
Moving the rear position of the lower control arm at the frame in or out, will change the caster angle significantly
and camber angle only slightly. To maintain the camber angle while adjusting caster, move the rear of the lower
control arm in or out. Then move the front of the lower control arm slightly in the opposite direction.

CAMBER
Move both the front and rear of the lower control arm together in or out. This will change the camber angle significantly
and caster angle slightly.
After adjustment is made tighten the lower control arm bolt & nuts to FRONT169 N·m (125 ft. lbs.) and the REAR
88 N·m (65 ft. lbs.).

TOE ADJUSTMENT
The wheel toe position adjustment is the final adjustment.
1. Start the engine and turn wheels both ways before
straightening the wheels. Secure the steering
wheel with the front wheels in the straight-ahead
position.
2. Loosen the tie rod jam nuts (3).
NOTE: Each front wheel should be adjusted for
one-half of the total toe position specification.
This will ensure the steering wheel will be centered
when the wheels are positioned straightahead.
3. Adjust the wheel toe position by turning the inner
tie rod (4) as necessary.
4. Tighten the tie rod jam nut (3) to 75N·m (55 ft. lbs.).
5. Verify the specifications.
6. Turn off engine.

Hope this helps

Thanks for all the info mate.

I read up on the manual before I took the car there.

It is definitely + camber.

I have a feeling that I am going to have to attempt some brute force at home under the car, then take it for a final alignment and give them the manual print out .

Hi Guys,

Just finished installing my superlift and had it wheel aligned. Happy with the lift but the aligner could not get the Camber adjusted perfect on the passenger side but not a biggy if you look closely you can just see it (+camber) also its slightly stiff when hitting bumps at the front and fair bit of bumpsteer, is there anything I can adjust to overcome this?

You might be able to slot the holes a little more,wouldnt need much
