I posted this on the list last weekend and only got a few replies -
everyone must be outside enjoying their TR's. Apologize for the repost
- but I know I've seen answers for this on the list before.
snip:
It's been quite a while since I've submitted a request for help, but now
that the TR6 is out of winter storage I need to once again address my
rear suspension woes.
I attempted to rebuild the rear suspension two years ago. At the time,
I put in new rear springs, up-rated rubber trailing arm bushings and a
single Moss coil spring spacer to compensate for the greater sag on the
driver's side of the car (must have been a helluva big DPO!).
Despite all this work, I've still got too much negative rear suspension
camber (ie sag) and have found, much to my dismay, that the trailing
arms have, over time, worked their way across the press-fit rubber
bushings until they're contacting the trailing arm brackets - which does
further wonders for the alignment of the rear suspension.
I have two questions. Question #1: has anyone got a method to take up
the excess camber or sag? I've heard stories of mixing and matching
trailing arm brackets (by a mix of one notch, two notch, three notch,
right side up or up side down brackets) to adjust the camber. In fact,
an experienced TR mechanic has suggested that I swap the inner and outer
brackets to fix this. Has anyone done this? If so, has anyone figured
out the geometric relationship between the bracket mix and the camber
that results? Or, should I forget about the brackets and make-up some
custom made coil spring shims to compensate for the camber?
Question #2: has anyone experienced this migration of the trailing arms
across the rubber bushings? Is it merely a question of rear suspension
alignment or something more serious at work here? The trailing arm
bushes in question don't have any shoulders but I'm told by the tech
expert at Moss that these bushings haven't had shoulders for years. One
of the replies I got back to my original post has indicated that TRF
bushings have a small ridge molded in at their ends. If so, is this
ridge big enough to stop the migration?
Thanks again for your patience.
