TR4 Steering Update
After the steering rack "freshening" was finished I decided to splurge on a 4-wheel laser alignment to see how everything is actually situated and to give myself some future datum points. The local Goodyear place actually had the car in their laser alignment computer.
I got the Toe-in set and learned a couple of interesting things. Firstly, while my caster was correct on one side it is out on the other; I had it all apart before and didn't notice any damage. Also, my rear axle is slightly twisted around causing a small + toe on one side and a corresponding - toe on the other; +/- 0.3 of a degree. This explains why I couldn't set the string equal when I was trying to do a string alignment. I had taken the axle out when the car came out of the barn. It looks like I can reset it just by loosening and re-tightening the bolts after giving it a "technical tap" to pivot it around slightly.
The steering is now nice and tight and the car tucks into tight bends very nicely. Also, the drive back showed the car to be much less twitchy at speed now it was negative tow and not positive as it was before.
Any thoughts on the caster discrepancy?
