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.
Rear seal leaked...had it replaced
Found leaking a little at time of service, and require replacement over $600 which includes labor.
Both rear end axils are leaking at rear end differential
axle seals leak... bad..
Had a funny smell from the driver side rear tire. Then was driving and rear end locked right up. Waiting to see exactly what's wrong
My car makes a roaring sound from the rear when in motion. Haven't got it fixed yet
Saw fluid leaking onto my driveway. Plugged vent caused seals to fail.
I started having this problem at about the 70-75000 mile mark.
Rear differential and axle seals had to be replaced.
I have not had it fixed yet but will within a week or two. I have delayed the repair for a while because it is $1000 and I keep forgetting about it.
When i drive to stop and start bad suond in the back.
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.
