Diff shimming

[stocky]

I've got a bit of whining coming from my diff at around 80km/h, and have been told I need to reshim the diff so that the crownwheel and pinion line up properly. I might give it a shot myself, but has anyone else done this before? also, does anyone know what size shims i use and where to get them?

thats a different kind of shimming. thats lsd shimming. mine is adjusting the shims in the centre to get the crownwheel and pinion to turn properly

yea i understand that but i was wondering if i can shim it myself like nissan lego parts cars or is it a bit tricky, and probably best left to someone who has a bit more experience

and do holden sell the lsd shims?

the shims that go under the pinion you can by of the shelf in different thicknesses. can't remember the size infortunatly. the "shims" that are used to locate the diff center are usually "surface ground" to get the correct thickness. normally between 3-4mm and are done indervidually for each diff so not an off the shelf item.

as for shimming the actuall diff center. best bet is to remove the center yourself and take to a local diff shop. they will be able to strip and shim the diff center in about 15mins (assuming it isn't rooted). if it hasn't already being done, they can replace the spring also as the spring fitted from factory is fairly average.

im just trying to decide if i should take it to a diff shop or try it myself. i can take apart the diff and get the centre out myself fine, but id have to buy the special grease for it to work out how far out it is, then the shims, then work out which ones to use, etc

i would. ifyou do it andget it wrong your stuffed, they do it and get it wrong you have some sort of comeback. they also have the gear and it shoudn't take long or cost much
