    They made two different rear main seals for that year. If you have a 1 piece rear main you have to drop the torque converter and pull the whole rear main as a unit. If you have the 2 piece its easy you just drop the oil pan and pull off the bottom halt and knock the upper half out carefully with a phillips head screw driver oil up the new one and toss it in, replace the oil pan gasket and your good to go. There is a code in your glove box code list that will tell you if you're a one piece or two rear main.

It is kinda difficult. if your lucky you can just take the inspection plate off the bell housing of the trans. but in my experience i had to drop the trans. and you have to get a seal puller. the seal itself is easy just getting to it can become a little difficult

SOURCE: rear main seal is leaking on a Ford Mustang 2003 V-6

In order to replace the rear main seal u have to pull the transmission out to access it, u will need a special seal installer tool to install the new rear main "full circle seal", it u don't use the special ford tool the seal will leak again, also if there is a groove worn ion the crankshaft the crank must be repaired or replaced or the or the seal will leak again, so this is avery diff job, a 9 on the scale of 1-10 with 10 being the mos difficult.

Yes, the seal has a pressed fit and is bolted on te rear of the engine, in fact all japanese cars do that, keeps them from leaking for a long time.

SOURCE: how do you change a rear main oil seal in a 2000 toyota celica gt

First of all, be certain that the leak is in fact from that seal. many leaks travel to that area.

To change the seal is fairly involved, you need to pull the trans and flywheel. There are some specialzed tools involved. Do you have manual or automatic? Manual requires clutch plate alignment on re assembly, by the way , if manual, be sure to change the release bearing and pilot bearing at minimum. Commonly it would make sense to change the clutch during this process....you're already all the way in there..

SOURCE: i need to replace the rear main seal on my 95

Yes you do have to drop the transmission, A good transmission shop can and will replace the rear engine seal for you in about 3 hours and there more experienced in dropping the transmission then any other shops, so it may be better for you the have the rear main seal on your engine replaced at a transmission shop. Good luck and hope this helps.

Is the rear main seal on a 1999 gmc yukon a 1 piece or 2 piece seal. Leaking oil real bad from back of motor.


its a one piece. should be the metal one with the rubber inside seal. of corse you gatta pull the tranny but its a good time to change fluids and maybe slap a new torque converter in. changing the rear main is pretty easy after the tranny is out.

I need to replace the rear main seal on my 95 chevy pickup with a 350. do i need to drop the tranny?


Yes, either pull the trans or pull the engine. No way to get in there with out having one of the two out!
FYI it's very rare for a rear main on that engine to leak, Most all of the time it's the oil pan gasket or coming from higher up like a valve cover or the intake gaskets!
