Awhile ago I swapped out the original A4LD from my 93 with 144k on it due to 'squeak n creak' noises when in reverse and fears that if left unchecked rapid unscheduled disassembly of the internals would take place in short order. Disassembly of the unit shows that it is in excellent condition with the only area of concern being the reverse drum and corresponding thrust (weave) washer which appears well worn. Questions - Is this discoloration 'normal' for a high mileage A4LD? I have another A4LD 'in a box' that has similar discoloration on the reverse drum, however, the very few units that I can find online for sale as used do not have this discoloration. - Provided that there are no dimensional issues (warping etc) with this part is it reusable as is? (servicing the sprag and other assemblies of course) - Is it normal for the sprag cover to just fall out the back of these? Mine showed evidence of rotational damage as if it had been flopping around in the case rubbing on something.
