Rear seals leak. Bought new oem seals. Used diff from scrap yard. Carefully installed all the"new" components.. One week later both new seals leak.. I'm not happy with chrysler. I love my 300 but this is bs. I had two mechanics do a meticulous job on this diff replacement because i heard the diff seals are sensitive. Looks to me like oem seals are just pai plain defective and chrysler won't do anything about it.
Leaks had been taking place for awhile, so they had gummed up and sealed. Had it fixed, but very difficult at a shop that doesn't have the special tools that a Chrysler dealer has.
After only 14 months, recurring problems. As of today 08/15/11, every four months replacement, adjustment, cleaning, something... It appears may be related to vent position. Keeping fingers crossed.
During an inspection it was determined that the rear differential/axle was starting to leak. I checked with dealer to get it repaired under warrenty. They had a seal in stock and did the repair. It then leaked more then before I had it in. They ordered anoter seal and installed it. No problem since then.
