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.
My car makes a roaring sound from the rear when in motion. Haven't got it fixed yet
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..
Axle seal leaking. I just purchased this car from dealer. Estimate for repair is $200
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
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.
