pretty simple job, a bit cramped for non-regular diy'ers. depending on the tools you have available.

secure the vehicle on stands (or lift, if available)

remove the belts

remove the crank bolt (an impact gun works well here...)

remove the balancer, crank gear, and hub.

remove old oil seal.



since the housing is aluminum, i do not suggest banging the new seal in without lots of caution as to not damage anything. you may wish to size up the new seal with a socket*, or, use a piece of pvc pipe and washer(s) and use the crank bolt to seat the new seal.

*a regular seal driver will not work due to the snout of the crankshaft sticking out beyond the lip of the timing cover.


other than that it's pretty simple. i do suggest proper torque specs, though. the crank bolt is listed at 303ft lbs, and is suggested to be replaced with a new one. (might be torque to yield design, not sure)
