TR6 TR6 Trunion resleeving?

[ichthos]

Trunions are running 65-75 dollars currently. It seems like the main wear would be where the pivot bolt goes through. Is there some reason why these would just not be releeved?

Unless the trunion is damaged, that is the normal practice. They aren't really "resleeved" rather there is a steel tube and bushings which are replaced. There are a set of o-rings and thin metal caps which keep it clean.

Actually, if you look at a properly assembled unit, you will see that the trunion does not ride on the pivot bolt, it rides on a nylon bush that rides on a distance sleeve that fits over the pivot bolt which, with proper spacers holds everything together. There is really very little area where a properly assembled unit will wear in the pivot hole of a trunion out.


The threaded part of the trunion is fighting two forces, the spring trying to pull it apart and the axle and vertical link flexing it along the vertical axis. As you turn the wheel, the threads and the vertical link are subject to the greatest forces of wear.

Prior to the TR4A, the trunion had a shaft pressed into it that rotated in bushes in the suspension arms. Looking back at your previous post, I wonder if some PO installed a TR4 suspension component (or stupidly jambed a larger diameter bolt into you suspension).

Even though I once owned a TR4, I cannot give you advice as to whether the A arms are the same as the TR6. If they are, then $80 will get you a kit to do both sides, and of course the new trunions for the 6.
