This video shows you how to install a rear axle bearing on your 2003-2011 Mercury Grand Marquis. If you hear a grinding or groaning noise while your vehicle is rolling, it might have a worn out wheel bearing. A worn bearing can allow the wheel to wobble, creating a host of other issues. To save yourself from more headaches down the road, replace your bearing right away. For solid rear axles, you'll need to replace the axle seal too.
This repair was done on a 2009 Mercury Grand Marquis LS 4.6L Sedan 4-Door RWD Automatic and the process should be similar on the following vehicles:
2003 Mercury Grand Marquis
2004 Mercury Grand Marquis

I paid a "Transmission Garage" $1800 some 50'000 miles ago for repairing my Diff in my 2003 Grand Marquis. Passenger side is now leaking again. So after watching this excellent video decided to have a DIY. After removing the wheel, caliper, rotator and ABS sensor I read the words 'INDIA' on the axel which raised my suspicion of cheap replacement parts. Next was to remove the fill plug and cover but immediately noticed the three bolt top bracket had never been put back. Drained the Diff of oil and found that the amount of sludge proved that they had not cleaned out the sump then to my horror discovered they had rounded off the 8mm retaing bolt. I managed to unbolt it with 5/16 and some leverage keeping the spanner from sliping away. Removed the 'C' ring washer but cannot 'remove/take out' the axcel. Seems like the end bevel on the axel will notpass through the cog wheel. I can push the axel back into place and put the 'C' washer and main rod back in place, then remove them again, but same thing. Any advice help would be appreciated. P.S This garage went out of business a month after the repair.

Great video..... 08:32 if you are going to pull the bearing as well, just pull the bearing and seal together as one, so much easier and less chance of damaging the axle tube..

[@grafduke7485]

Great video! Question: why is the tag (attached to the bolt at 04:59l important? Why hang on to it? What is this tag for?

[@TheRancher03]

Using your video, I replaced both rear axle bearings this morning in 3 hours (mostly cleaning the cover) but did wait 2 hours to torque the differential cover to 33 ft lbs after coating both sides of the reusable gasket. The cover was obviously torqued too early previously since only the inner and outer sides of the cover had gasket maker. I reinstall the pinion bolt when working on each side like the FORD manual asks.to do. The torque for the ABS is 18 inch lbs and cover bolts is 33 ft lbs.

How is alignment shop going to help in the end?…

[@UncleSarkis]

When putting the C-clip back in, does it matter if you have the rounded edge facing outboard or inboard?

[@hectorotani27]

great vid , for the alignment question in my case car got rear ended bent axle and pushed the driver side inward so alignment shop it is, for others if car hit curb bent wheel it could throw rearend out of alignment.

For axel removal ?

[@TheeMissingLinc]

You do not need an alignment, in fact there is no such thing as a rear alignment in any panther platform vehicle, ie Crown Vic, Grand Marquis, Towncar
