The passenger side cv joint was bad on my 93 Corolla wagon so we replaced the shaft & now have a slight tranny fluid leak from where the shaft enters the tranny. I put it up on ramps the other day & sprayed everything down with brake cleaner then started it up & ran it for a few min & didn't see any leaks so thought I was good. Two days later I put it up again & it is leaking down & dripping off the tranny. Not a big leak, only had to put 3 oz to bring it back up but I don't like ANY leak & want it fixed. What type of seal is in there & how hard is it to replace & what if any special tools such as seal puller, etc. is needed to do this? I will be doing this with the neighbor & want to order whatever is necessary to do the seal so its here by the time we do it. It is the 4 speed auto trans & 7AFE 1.8L engine.

Thanks,
Steve

pull the axle and replace the axle seal, like you should have done the first time remember to lube the axle and seal well so when you put the axle in you dont tear the new seal.

you can use a flatblade screwdriver to pry the old seal out and a large socket to drive the new seal in. or you can probably rent the seal driver kit.

yep, that happened to me once or twice as well. You could usually get away without having to replace the seal if you are very careful when sliding the half shaft back in.

What is the best thing to lube the seal & axle with, grease?

 

[Bitter]

just use either trans fluid or petroleum jelly. either will work just fine, i'd suggest trans fluid since you already have some leaking right there! dunk the seals in it before installing and lube the axles up in it as well, the splines and especially where the seals ride.

Be sure to have the shaft started into the differential gear before sliding it home. If you come in at an angle you can damage the seal.

I have a seal puller & seal driver set coming, hope to get it done next weekend. Thanks.

honestly you dont even ned a puller. I borrowed one from autozone just in case but ended up just pulling it out with a large screw driver with almost no force.

If you use the puller be careful not to dig too deep and score the seat. The seal is flimsy and easy to cut through.
