1979 chevy truck 1/2 ton. Has a clonk when put into gear. I have been told that I may get away with shimming it, but thats one thing I have never done. Any links to pictures or stematics would be helpful to see how it is done. Thanks.

I have been driving it everyday for the last 4 years. It does not seem to be getting any worse, it is just starting to annoy me. The auto zone link is great, thanks. I like the idea of a salvage replacment also.

what about the pinion gear,is it lose?when you get into the ring gear,you got to have the right pinion pattern.if you get it off,then you will tear off the teeth off the ring gear or the spider gears.ill tell the best thing to do,is go to the salvage yard and get another rear end.that would save a lot of hassle and headaches.if you dont want to change the whole housing,just change the pumpkin.

You should first determine where the true problem is. The clonk could also be in the transmission or drive shafts. You should probably start by checking the u-joints in the drive shaft.
If the problem is in the differential you probably can not solve it just by re-shimming. You will first have to address the part failure or excessive wear that is causing the clonk.
The differential shims are installed to account for variations in the manufacture and machining of the housing, gears, and bearings in the differential. Replacement of parts in the differential generally require replacing the shims to account for the replacement part.
Re-shimming the differential is a complex task requiring tooling and experience that most shade tree mechanics do not have.
You will first of all need a shim kit containing the various shims for your differential. The shimming process is a trial and error process where you measure the gear backlash and observe the gear contact pattern as you try different shims.
This requires micrometers and gauges to accurately measure the shims and the backlash.
You will also need a colored paste such as Dykem Hi-spot. You brush this on the gear teeth so that you can observe the gear contact pattern. You will also need to be able to recognize when the contact pattern is correct.
