Noisy diff

[Webber]

Hi folks I'm new to this site so please bear with me, I have a 1982gl godwing trike with reliant rear axle, when taking off thru the gears it pulls like a train, problem is soon as trike starts to coast or slowing down it sounds like trike is dragging a sack of spanners behind, any info would be much appreciated (summers comming)

if im right is just when u ease off on the trottle and it last about 2/3 seconds

Reliant axles are a bit agricultural and are all a bit 'long in the tooth' now so there is backlash between the gears that only shows itself on over-run when the wheels are driving the diff. Diff's can be re-shimmed to minimise the slack (not a DIY job really) but there will always be some - it'll sound mechanical rather than a toolbox mounted on a jack hammer LOL!

A bit of backlash will be a clunk when going from power to overun, not like a bag of spanners. You need to have a look inside it.

Drain the oil and check it for metal bits. Some very small parts are ok like fine flakes.

Check the ujs on the prop shaft and the splines on the back of the engine where the shaft fits onto
