Is it hard to change the rear end input seal which is leaking gear oil? and about how much for the parts? ?

my 95 toyota 4runner has a rear end leak coming from a seal where the drive shaft meets the rear end. my 4 runner is 2WD. is this a hard job for one person and will i need special heavy duty tools, or will i run into some problems during the R%26amp;R? the seal didnt leak until i took the truck to the mountains and i guess the extra torque wore out the seal and now it leaks. its not a serious leak, but it stains the concrete driveway. by the way, any tips for getting oil stains out of concrete? any help is appreciated. sukiIs it hard to change the rear end input seal which is leaking gear oil? and about how much for the parts? ?
That Rear Seal isn't hard to change, but you will need a 3/4 inch impact and there's that Crush sleeve that will requires the use of a 300 ft.lbs. Torque wrench.


Don't forget to mark your Drive shaft to reduce the chance of throwing off the Drive shaft Balance.


Parts should around $38.


Good luck
