Mercury Mariner Problem Report
Mercury Mariner Transmission Oil Leaks from Left Side Half Shaft Area
If the transmission oil leaks out of left side half shaft area, it may be from a worn axle shaft seal. The seal can be damaged by a poor surface finish on the axle shaft. The axle shaft and seal should be replaced to correct the problem.
Transmission fluid was leaking from driver side axle shaft. Ford replaced this part and corrected the problem. My local Gurnee, IL ford was thorough. - Visitor
My 2009 Mercury Marina was leaking oil from the left side Half shaft seal and bearing like so many others . Now the same thing is happening on the Right side seal and bearing area. Been back and forth with Ford on this as my car is 14 days over the 100,000 mile 5yr warranty. I stuck to my guns with this issue and only because of the low mileage. Ford did repair the left side, but now I am having a waiting period to get the right side done. The garage (Ford) said it was a trans oil filler dipstick tube that was leaking but they have been wrong on this as they fixed that and it is still leaking bad. Getting a little upset with going back and forth with Ford on getting this nuisance oil leak fixed right. Great car for the little use I give it, these things should not occur at this mileage. - Visitor
leakage of transmission fluid on left side, axle leakage - Visitor
I was told I have a transmission half case leak. I just can't believe this because I am original owner and consider my car still new!! I have done regular maintenance on it and mostly highway driving, very seldom over 65 mph! I think ford should cover this defect as I see how many others have had the same problem!!! very very upset - given an estimate of $4100 to repair. - Visitor
Heard a ticking sound coming from the vehicle. Pulled over and checked all the fluids. All the transmission fluid was gone. I took it to the dealer and they told me the half shaft was needing replaced. Luckily my extended warranty covered the cost. - Visitor

Car started slipping in gears on take off and i checked fluid and it was low. I took it to a transmission shop and he said i am losing fluid on the left side shaft area. I just bought my Mariner in November of 2011 it was a lease turn in. I love it but i cant believe i am having mechanical problems already. - Visitor
axle seal replaced and lasted less than 2 months. Going back to dealer tomorrow for more repairs, possibly replacing axle assembly. - Visitor
bought car used, put a total of 400 miles on in 5 months, last oil change 5 weeks ago, noticed oil on garage floor, mechanic said it was a possible transmission axle seal leak, what a freakin bummer, dont want the car now. - Visitor
Noticed fluid dripping. Discovered where axile drive shaft slides into differential. Calling Ford dealer to get repaired had 6 year warranty maybe close running out of warranty. - Visitor
I have the same problem. Axle shaft seal leaking left front side. Alot of play. - Visitor
Purchased car used from a local Ford dealership and the next day my mechanic noticed the axle seal leaking. Ford dealership confirmed they had just replaced it 200 miles earlier, but in the meantime (1/26/12) Ford issued a service bulletin on this and Ford paid for a proper repair (basically a new left axle). If you've already paid for this repair it might be worth asking Ford for a refund as they've recognized it as vehicle flaw in the manufacturing. Good luck to all! - Visitor
