New type of diff shim!
I am a manager at a tire/automotive shop in addition I do all my own maitninace and custom work on my vehicals. A wile back my A/C wasn't working but simply the clutch wasn't holding. I talked to another one of the mechanics and he told me often you need to shim the clutch. Well I still had some of the shims and the ones I ordered on ebay won't be here for 3-5 days.
I had to look at my diff because it was clicking bad. sure enought the shims worked perfectly! I will compare them to what the associated ones look like but it seems as if it is a local fix if you have a parts store and not a hobby store! I am not sure how price stacks up either.
