TR2/3/3A Distance from center wheel hub to center wheel hub?

[karls59tr]

I'm trying find what the distance is from the "center hub on the front wheel to the center hub on the rear wheel on one side of the car" compared to the other side of the car. I believe the rear axle is mounted somewhat crooked because of the car pulling to the left on acceleration. I'm putting the car up on jack stands tomorrow to see if everything is tightened down properly and if there are any irregularities in the set up. Anyone know what the stock spec would be?

I think that dimension is the wheelbase and listed a 88 inches exactly.

Thanks Tom. I'm getting 87 1/4" on the driver's side and 88 3/4 on the pass side. I remember now that I had a heck of a time getting the front lef spring bolt out of the frame on the passenger side and ended up drilling and reaming out the bolt hole. I think i may have enlarged the hole and the replacement bolt is on a bit of an angle towards the back...I did manage to get the leaf spring on though!
I wonder if there is any way to move the axle a bit at the "U bolts" or do I have to realign that d$%n front leaf spring bolt and reweld it?

I don't think that bolt could be that far off (some slight variation left to right is not unusual). However, if the bolt is loose in the frame, or badly misaligned, you will need to deal with it, and that might cure the problem.
I'd still take some additional measurements of the rear axle compared to reference points on each side of the frame to confirm that the wheelbase discrepency is in the rear. If so, pull the ubolts and make sure everything is lined up properly. Finally take a close look at the main leaf in the spring to make sure it isn't broken. Might also be worthwhile to get a printout from an alignment shop.

I wouldn't use the front wheels as a measuring point, as after all these years every hub/wishbone assembly I have encountered has been tweeked...at best. You need to measure to frame points, and the frame section of the service manual gives you some detailed points to take the measurements from. Use a simple plumb-bob and transfer the points from the frame down to the pavement...then measure on your pavement marks. It's a crude way, but it'll tell you if the spring mounts are off enough to cause your problems.

Good idea John.:eagerness:

Hi, I checked the same relationship with a Stanley construction laser. Mount it to a 2x4 and hold it on the rear tire, projecting forward. Get a dimension off the front spindle or fender. The rear track is wider than the front so its pretty easy. Check the rims to make sure they are not bent, it will throw of
f the dimensions. Repeat on the other side.

I had to drill out the old spring bolts also. Its not fun!

Good luck,
