Knock when accelerating - Diff? Drive shaft? Bushes?

[DJW]

Hi, gents,

I'm getting a knock every now and again on the zed. Sometimes after a gear change, but I don't think it's the gearbox as I'll also get it when I'm not changing gear - the common denominator is that I'll be accelerating in some way when I get a knock - just the one knock - Any thoughts on where I should start? What might the most likely offender be?

Thanks all

Cheers

Hmm i have the same issue! I have changed all anti roll bar bushes and links and still have it. Normally notice it at slow speeds when stopping and starting in traffic.

Im thinking a engine/gearbox mount maybe?

Propshaft donut coupling would be first thing to inspect - quite common and well documented on here. Not a difficult job but you do need to drop the exhaust IIRC... https://z4-forum.com/forum/viewtopic.php?f=3&t=97640&hilit=donut
