My moms explorer is leaking oil really bad from the front main on her 4.0. how hard is it to change the front main............i have the knowledge and the tools.....just need to know how hard it is to do....

 

if im thinkin of the same thing..i think you gotta drop the tranny down..

 

front main not the rear main seal

 

$20 for a Haynes manual ought to let you know if it's something you want to tackle.

 

i have a haynes manual for my truck with the 4.0(same engine as her exploder) but couldnt find it in there......

 

see told yah i dont know what im doing lol..but hey if her rear main goes out..you need to drop the tranny

 

look at changing the timing belt in the haynes. Isn't the seal built into the timing cover?

 

She might have a grooved balancer. If so replacing the seal won't be all you need. They should make a repair sleeve for the 4.0. If it is grooved, clean the balancer and fill the groove with JB weld or whatever, sand and polish it down to the original diameter and install the repair sleeve. When I lack time, I have installed the sleeve and not changed the seal, saved me time and it worked every time I tried it. Time saved is in front cover gasket , and the supreme care required to not have / cause a leak at the pan ; if you aren't changing that gasket also. Good luck , bob

 

Bob, is this the plastic piece between the crankshaft and the pulley?

There are a few guys around that have put the 4.0 underdrive crank pulley on so there should be some used original pulleys out there.
