Thread: Driveline Backlash

Another thing to look for is the nuts that secure the universal joint flange to the hand brake drum. I found free play there once as the nuts had come loose. If this is the case, tighten them and after a month or so check them again. The stud can stretch meaning the tapered spline that locks them into the brake drum doesn't do it's job any more. If they stay tight they are OK.

In my experience there are no studs with tapered splines. They are bolts though the drive flange and one of the flats on the hexagon bolt head is against the boss so the bolt can't rotate. A retaining ring (circlip) prevents the bolts moving inward when the nuts are removed.

The brake drum is sandwiched between the drive flange and the u-joint.
