After trying to send this twice and not showing up I have gone to the Part 1
and Part 2 solution, sorry....
Hi List,
I wanted to give the list an update on a frame problem that had developed on
my car. If you would like to see pictures of what is described in this email,
go to triumphowners.com/108 and click on the photo entries for Rear Shock
Conversion Problems.
A year plus or so I installed a rear tube shock conversion kit from John
Horton. I had used the kit with no problems for quite awhile but in late July I
noticed a noise coming from the rear suspension and decided to see what the
problem was. Looking through the wheels I could see the frame was cracked
around the differential mounting bracket. I took it over to Rick's house and we
put the car on the lift for an inspection. We discovered that where the frame
and the differential bracket met there were quite a few cracks. Basically,
every place that the frame met had either started to crack or most of them were
all the way through. I believe the noise I heard was the differential mounting
bracket moving on the frame. The drivers side was slightly worse than the
passenger side but both were pretty bad. With Rick at the welder everything was
cleaned up to provide clean metal for welding and then the cracks were welded.
As an extra measure of strength the bottom 8 inches of the d!
ifferential bracket was boxed in.
Before the repair we pulled down on the body to see what was happening and it
was clear that as the suspension deflected downward the shock bracket traveled
towards the back of the car, putting a great deal of stress on the differential
bracket. Now I wont pretend that my frame was newly replaced or that it is
perfect or has never had any rust on it. But I think it is typical of what you
might find for a 35 year old frame and there were no apparent problems at the
time of the install.
Part 2 to follow....
