Looking for suggestions and expertise

So Newman was following me back from HH and noticed the 90 was "dog-Legging" down the road with the rear of the truck tracking to the right of the front. When I got back to the house I wrapped a string around all four tires to check alignment and this is what I have found. Pic 1 shows the 1"space between string and tire, at the front of the rear left tire. The front tires looked good. I also looked at the rear wheels and how they were centered in the wheel opening, pic 2, the rear left tire sits about .5" to 3/4" further to the front compared to the opposite tire, and as confirmed by the string.

See crude pic for my illustration as to what is going on.

I will pull the stock trailing arms down and check bushings, but he frame side bushings are the orange poly and look good on both sides

Solution?
1. Adjustable trailing arms, nut in the budget.
2. Space out the shorter (left) trailing arm
3. Shorten, some how, the longer (right) arm
4. Do a little of both.

You are assuming it is the rear, but is the truck lifted? If so, the panhard pulls the front axle to one side. I suggest having an alignment shop get you accurate findings before doing anything.

Sitting stock right now. but noticed rear spring seats are pretty crusty, probably doesn't help.


I am scared of most of the "alignment" shops around my location. If the machine doesn't tell them they make something up, but will ask around.

Our guys have the laser alignment, and it is pretty accurate. I just think you need an accurate base line before starting to change things. Also, if the front springs are sagging, the axle moves the opposite from lifting....

Good point, does currently sit 1/4 lower in front. I have 2" lift springs and new shocks and spring seats, HD steering rods w/TREs ready to go in. Worth installing then sort this out with healthy components installed?

Another easy thing to check before spending money is:

1. Measure lengths of trailing arms.
2. Measure positions of rear trailing arm mounts on frame relative to front radius arm mounts.

All it takes is some tape measure.

And just to clarify the rear axle looks to the eye and measures miss aligned, as exaggerated in the crude drawing. Not saying the front is perfectly aligned but rear seems to me more of the culprit.

will take more measurements this afternoon. I did It quickly and noticed some variance but cant remember the details.

This. A few minutes with a tape measure will shed some light on it. Check the integrity of your bushings and make sure the trailing arms aren't bent.
Also, you drive a Land Rover and its entirely possible things are a little........off. The rear axle on my '98 D1 sat further to the drivers side than it did the passenger side.

You can space the trailing arms very easily with a few big washers from Home Depot.

You could also have bend axles, so it is probably best t get an a check with a 4 wheel alignment machine to see where everything is before trying to correct things. A string test can be misleading.

No. New rear crossmember, but frame is solid and looks to be straight with no impacts/damage

Measured trailing arm mounts to frame. Like mentioned above. Truck must have been a friday build. 1/4 inch more forward on left side. Added 1/4 inch spacer and seems about perfect. Moving forward to replacing spring seats and lift springs..
