Yes, this will usually occure at a point one year after the initial installation and the contractor who installed it can usually help with the sealer. Terry
Should pull the drive pulley and then you can pop off the old seal with a screw drive and press in the new seal.
It is generally safe to drive on concrete after 5 days of it being poured, but it is recommended to wait at least 7 days to allow it to fully cure and strengthen.
The drive shaft does not leak. It is either the pinion seal or the trans. seal. Either one, the drive shaft has to be removed. The rear seal should be done at a garage, but you could do the front.
Front seal: remove engine or transmission and replace the seal. Rear seal, remove the drive shaft to replace the seal. Unfortunately, you typically only have problems with the front seal.
You must remove the drive shaft. But first block the wheels so truck don't roll. Now take a screew driver a hammer and drive the seal out, you will loose some fluid but not much. If your good you can drive the new seal in with a hammer. If not they do make a seal driver that a parts store might rent you. If you still have a leak and your sure its coming from the seal and not the yoke on the drive shaft. Then the bushing in the trans. behind the seal needs replaced, and that can be trickey. Don't forget to polish the yoke on the drive shaft were it slides into the trans. GOOD LUCK
No you do not.
This 1950 classic movie starred Sterling Hayden, Louis Calhern and Jean Hagen.
Remove the engine and remove the flywheel or flexplate to expose the seal. Carefully pry out the seal with a screwdriver. Don't nick anything up. You will need a special pilot and drive tool to install the new seal. Make sure the seal says "This side out" facing out. Drive the seal in until the tool bottoms out. Then put it all back together.

Yes. Remove drive shaft from the differential (rear-end) and slide it off the splined shaft into the trans. A seal between the shaft & trans tail piece can be removed (prying sometimes) and a new be seated in with a block of wood & hammer. Inspect where the old seal rubbed the drive shaft for a too worn area. yes tranny tail shaft seal Yes, there is a rear transmission seal.
