Both rear end axils are leaking at rear end differential
Rear axle seals on right is already leaking. Car was purchased new. Is this a common problem or a recall item? I've never had this problem before so early with a vehicle.

Routine tire inspection before vacation; grease leaking from right rear axle near wheel (outboard, not inboard) - will cost about $500 to replace the axle and seal.

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.
