running a 760 gle 1989,here in the uk.
Ive just replaced the steering racks track arms,due to it failing the annual mot test,didnt think they were that bad!
Having to do this forced me to look again at setting the toe, in and doing this job myself, rather than just take it to a garage.
They all have the equipment for tracking,obviously costly items,but in my experience a baboon could do a better job.
Is it reasonable to expect a car to wear the front tyres evenly,instead of scuffing the edges off.I havent had a car yet (all joints in etc in A1 condition) that doesnt.
Have any brick boarders gone about doing their own wheel alignment,with home made testing rigs and achieved that perfect!¬ front tyre wear.
Any photos diagrams etc of such rigs,and experiences would be much appreciated.

I recently did a 100% rebuild on the front of my 93 940 and since the toe in is the only adjustment, did it myself. You will need a piece of spruce or pine at least 2 meters in length that is straight. (A piece of aluminum flat stock is great if it is available.)

1). Make certain that the steering wheel is in the center postion.

2). Place the straight edge lightly against the left front tire and adjust the toe in until the straight edge is parallel to the rocker panel (section under the front door), or parallel to a line struck from the rear tire with the straight edge. Either will do. (I run fairly large tires on my vehicles so I can check fron to rear without hitting the coach work.)

3). Adjust the right side toe in until the measurement between the centers of the tread in the back of the front tires is equal to the measurement between the centers of the front of the tires. You should be able to get the car within 1/8" and have not noticable wear.

4). Once you are satisfied with the adjustment, make a gauge from a piece of straight 2"x2" with a couple of nails for pointers. (JC Whitney sells a toe in tool)

I learned this from one of your fellow countrymen who did his own Jaguar, and there is no sign of wear on any of the three currently on the road.

My 760 has always worn somewhat unevenly. My '71 145 however has always been true. I recently set the toe in on the 145 using a tape measure. You can place dots on the front of the tires. Measure the distance between the dots. Roll the car forward (or backward) till the dots are on the back and measure again.

Here is a link i found. It's for a miata but the theory is the same.

there are some other sources.

Good luck.

Ill give all these suggestions ago many thanks.
Another point does anyone have experience, of using Gunsons trakrite unit for measuring tracking.
Theory is you drive onto it which measures any force due to incorrect tracking on a gauge....then adjust,apparently you dont even have to know your toe in settings
