Well the seal itself is not too costly and all you have to do is drop the drive shaft from the trans, remove the dust boot and remove the seal it won't take but 1/2 to remove and replace the seal

How to remove rear wheel bearings on my 1999 Ford Expedition and how do i know what pulley to rent/buy?

The 1999 Ford Expedition is built on an F150 platform. The Expedition uses a 9.75-inch rear axle. The axles are retained with C-clips at the end of the axle shaft, inside the differential carrier. The axle bearings are of the roller type. A failed axle bearing can manifest itself as a noise at the rear wheel or gear oil leaking past the oil seal. When replacing axle bearings, the oil seals must also be replaced.
Torque the caliper mounting bolts to 30 foot-pounds. Torque the bolt to 20 foot-pounds with a torque wrench and socket. Click this link below for complete detailed procedure:--- -------------- This should help.Thanks.Helpmech.

I have a 1999 ford expedition and need to replace the tail shaft seal on the transmission. how is this done

to replace the tailshaft seal, you need to remove the driveshaft. just unbolt the u-joint at the rear differential, be careful not to lose the caps to the u-joint. once you've got the driveshaft loose at the differential end, it just slips out of the transmission. use a small prybar or screwdriver to pop the old seal out, don't scratch or nick the aluminum housing. then just use a large socket or pipe that fits around the outer ring of the seal to drive it in flush.

00 ford expedition rear self leveling system

Try jacking up the vehicle and putting it on jack stands letting the suspension hang down. Disconnect the battery for a few minuts and reconnect it and it should inflate the airbags and level off the suspension.

1999 ford expedition - rear main seal leaking

I don't know why your mechanic needs a picture of the seal. Here is what you will need to do. The tranny will need to be removed because your vehicle has a one piece real seal. After you remove the tranny remove the flywheel then you have access to the rear main seal. If you have never removed a tranny leave it to someone capable of the job. You will need many tools to remove the tranny and a little muscle here and there. It is an easy process for a mechanic, but labor intensive.

Rear transmission leak

it sounds like you have a tail shaft seal gone in the transmission it's not a difficult fix if you are handy. Remove the drive shaft and remove the tail stock seal(there are install and removal tools but a hammer and a screwdriver will remove it nicely)then replace with new seal (if you don't have the install tool a 5" long piece of 2x4 and a hammer works BE GENTLE!!!!)and reinstall drive shaft..........these seals are available at your local auto parts store and are usually no more tan $10.00
hope this helps!.........good luck!
