Farmall tractor how do I replace the front oil seal on transmission drive shaft of farmall md

remove the drive shaft ( tail shaft) lever out the old seal. put sealer around new seal and fit back in extension housing. Use something that is the same size as the outer edge of the seal and tap it in flush with the edge of the transmission housing. Expect some oil to drain out when the tail shaft and seal is removed

You don't say, Front or rear wheel drive. First check oil level, On rear wheel drive check the thrower plate on the tail shaft at the diff end is not bent and rubbing on the seal, A dry oil seal can make this noise.so can the U/Joints. on front wheel drive , check the cv joints , dry oil seals , the drive shaft inner cv joints have a thrower plate that may be bent. worn or binding brakes can make this noise also.

you newed to pull the rear u bolts and take th drive shaft off then you can replace the seal its realy not hard

Is it engine oil or transmission fluid? Is it driven often or does it sit in the garage? If engine oil, then possibly the rear seal is leaking into the bellhousing as you drive and then draining on the floor after you stop. If ****** fluid, then possibly front seal on ****** is leaking. If car sits for long periods of time the input shaft seal can allow fluid to leak past the shaft. This usually will fix itself when driven. Can't promise it will fix itself permanently. Will not be an easy fix if either seal needs replacing (or cheap).

OIL LEAK AROUND THE SPARKS PLUGS COULD BE LEAKING VALVE COVER GASKETS ALLOWING OIL TO SEEP BY GASKET FLOW DOWN AROUND SPARK PLUGS.TRANSMISSION LEAK IS NOT VERY EXPENSIVE LONG AS TORQUE CONVERTER SHAFT SEAL NOT LEAKING WHICH TRANSMISSION HAS TO DROPPED OUT TO REPLACE SHAFT SEAL.IF TRANSMISSION LEAK AROUND FRONT AXLE SEAL IT MAY COST A LITTLE.BUT PAN GASKET LEAK OR OIL COOLER LINES WONT COST TOO MUCH NOT HARD TO GET TO REPAIR.PHONE AROUND GET PRICE CHECKS.

it is VERY unlikely that a seven year old car would need that much done to it, unless it had 200,000 or more miles on it. New oil should be the color of honey, not dark brown. That's the easy check.

hi there is 2 possibilities on this one, first the front oil seal that is on the input shaft that goes into the engine/motor, then there is the oil seals that are on the drive shafts where they pushe into the transmission, and this realy are the main ones...hope this helps

If you have never serviced the transmission, it just may be time to have the transmission fluid and filter to be replaced if the transmission fluid is leaking from the transmission pan. If it's leaking from the rear of the transmission where the drive shaft goes in to, then it's the rear seal from the transfer case and the seal needs to be replaced and the transfer case topped off with fluid. If the fluid is leaking from the front of the transmission where the engine connects to the transmission than it's a good chance that it's the torque converter or front pump main seal. The other place that it could be leaking from is the transmission oil lines from the transmission to the cool at the radiator. Please let me know if it's leaks worst when the engine is running or only when your parked for a few hours. Keep me posted, be glad to help. 

Yes it's a bad seal and most likely the side bearing to the trans axle is bad too. Once the bearing has play, it vibrates and causes the oil to leak though the seal. Note: if one side went bad the other side is soon to follow since they have the same amount of miles on them. Might as well change both side. Good luck and hope this helps. Keep an eye on the transmission fluid level, don't want to burn out the transmission.
