Knock, knock.....

[Sbend]

I have a cross-flow, live axle with 20,000 miles on the clock. Yesterday, under acceleration, I started to get a knocking sound from the rear of the car the frequency and volume of which increased with the speed. When I eased off, it virtually disappeared. It's obviously coming from something rotating, and just as obviously it's coming from the live axle. I'm going to take it apart this week-end, but before I do, has anyone else experienced this problem, and if so, can you give me any guidance as to what it might be?

Thanks for that. Checked and unfortunately the UJ is fine so it's going to be a strip-down.

Well, got the UJ's all checked out and freed up, but have now established that the problem is with the half shafts which have separated from their bearings, allowing the rear wheels to float in and out. Have new bearings ordered, but has anyone else dealt with this problem ? Will I need to shim between the shaft and bearing or can I rely on a press fit ? Would be grateful for any advice on this.

Hi Tony,
email me on [e-mail] and we can take it from there.
