Known as bump steer. Do your tie rods have the same number of threads showing between the spindle and the tie rod sleeve ?
In the drive way jack up the front end from the center of the K frame and measure the toe change on each side every time you pump
Good question! On the RH side, the amount of threads showing on each end of the tie rod sleeve is roughly the same. As for whether it is similar to the LH side, I will have to look.
One thing I did notice when I jacked the car up under the k-member is that the RH tire definitely turns in quite a bit more than the LH tire. I lifted the car until the tires are just barely and lightly touching the ground and you can watch the RH tire turning inward. So I definitely measure a toe-in change. I don't recall seeing much (certainly not nearly as much) toe change on the LH side so I'll have to go look at that again this evening.
I took measurements when I started and here is what I found (using a tape measure and recording to within 1/16"):
1. Car sitting on ground...toe-in essentially 0"
2. Jack car up under center of k-member until both front wheels are in the air then set it back down until both tires are slightly loaded touching the ground: toe-in measures a hefty 1.75"! I believe most of that is coming from the RH side.
I'll have a look at the tie-rod threads side to side tonight and report back. Thx!
