I got several responses on my questions about the u-joints on my wife's
TR250. Thank you everyone.
The general response was that the u-joints were probably bad. So I
started to remove the drive shaft. I could get the front bolts out of
the flange. The rear ones I can not get loose at all. I am using 2
fairly long (longer than the normal combination wrenches) box end
wrenches and can't get the nuts loose. I sprayed them with Kroil and
let them sit for overnight. Still no luck.
Does anyone have secret tools for getting to these bolts?
In the mean time a mechanic offered some advice that I thought I would
pass on. He suggested that I grease the u-joints, if they took a lot
of grease they were probably dry. Then take the car for a short
drive. If the sound is gone or changed, it was the u-joints in which
case I need to change them. If the noise is unchanged I have greased
the u-joints which they probably needed anyway, but then I need to look
for another cause for the noise.
I have greased the u-joints and put the bolts back in the front flange,
but have not taken the car for a drive yet to check out the noise.
Thank you,
Roger Elliott
