My 300D dodged the bullit of death the other day at the shop. I took her in for clear oil was leaking from the rear, and well, it turned out to be the diff seals. No biggie, however, when re-installing the axle shafts, the boots, which were on their way out started to crack! If this had happend on the road, this would have destroyed the axles, some $1200 a side to convert to the new flange types! WOW, I got away with just having to get new boots, thus saving the old shafts! What would have been the sure economical death of my car, just wound up being a much smaller expense.... Do yourselves a favor, take care of those boots!
