Reply to: RE>>TR6 driveshaft out of kilter
The slight angle of the drive shaft is perfectly normal. While the diff is in
the center of the car, note that the pinion is not. It and the ring gear are
off-set slightly, so that the drive shafts can be of equal length (prevents
torque steer).

Thanks for the response, Doug.
I'm curious to hear how this one turns out. The car would have had to take
quite a shot to scoot the diff over. The differential mounting is very
rigidly mounted to the frame (albeit, prone to cracking), and the mount
would not move over without taking the frame with it. Furthermore, the axle
is collapsible and the trailing arm mount points are located 2 feet away and
out of line with the differential mount point; so I'm having a hard time
picturing what type of accident would impact on the differential without
tearing the rest of the car all to hell.
I agree, though, that my theory of the car being built with a crooked
driveline sounds equally improbable :-) For weight-distribution and
structural stability, they'd have wanted both the engine and differential
smack on the centerline of the car.
So I vote even more strongly now for a body that doesn't sit squarely on the
chassis. Or maybe the prescription has run out on John's glasses and he
just hasn't realized it yet? :-)
When is this day gonna end...
