Hi Guys

The backlash on the rear diff is getting way too much. No lateral play on the pinion itself, but plenty when turning it anti/clock wise.
Gearmax in Pta wants to replace spider gears and side shaft gears without even looking at it (R5k - R7k)...I'm thinking it can be sorted by shimming it.

Any thoughts?

Hmmmm ....If it is indeed the spiders, shimming can work but I think it will be a temporary solution. Shim stock is usually soft and I think the spiders will wear through it in no time. If you can get a harder shim stock like stainless, that should work. :think:

If it's the crown and pinion you can set it up with the pre-load.

I hear you...but I doubt if gears are that worn, maybe I should just have a look myself

Personally I think it's more likely that the backlash is coming from the crown and pinion. :think:

Usually backlash is from the pinion and crown wheel.

Shimming way to go but quite time consuming.
