Diff problem

PostPost by: cusword » Tue Aug 31, 2004 6:08 pm

Thanks for replies to my earlier posting. I am now a little more
encouraged to get the job started, but now I want suggestions about
the problem.

There I was at Oulton Park attending the Gold Cup. When I got back
to the car all the other CLOGs had gone. I had a flat battery but
got a push. The car fired up but there was a 'click' and no drive.
I came home on a trailer, and now the car is on the drive with the
back end in the air. With the engine running, and in gear, the
propshaft turns, but neither wheel does. With the engine off if I
turn either wheel in either direction the other wheel does not
move. When I turn the left hand wheel the prop shaft does not
turn. When I turn the right hand wheel the propshaft turns, but
occasionally stops even though I am still turning the wheel.

Is it the diff, or a broken output shaft? Anyway, I will find out
soon when I get it off, but would be interested in any comments.

Funny things, diffs aren't they.

David,

I broke an output shaft first time out this past spring. It was a straight break, rather than a torsional failure, so there were no debris fragments to fall into the diff. I simply removed the half shaft and the offending output shaft. Never removed the diff from the car. I have a small pot type magnet, about 3/4" diam x 3/4 long, mounted on the end of a threaded rod. Thattool removed the splined end of the output shaft.

If you've had a torsional failure, the evidence will show a bunch of littlepie shaped chuncks. You will probably never get out all the debris and at that point, I would probably pull the diff to clean out all the swarf, but I'd pull the stub axle out first, to validate what the problem is. I'd guess it is the LH one.

David,
If you got the car started by a push start, does this not mean that the diff was working? Could it be that the diff broke because you got a push??
I left the Gold Cup (with Gareth and Phil) just as the last race was starting, after two days of excellent classic racing we thought that Formula Fordmight be a bit of a let-down. Sorry that we left you behind, it sounds like we could not have done much to help anyway. If you are thinking of getting a replacement diff try Steve Davies, who may be able to sort you out on an exchange basis.

Cheers,

Pete
