4HP22 Rear Output Seal Replacement?

[emil]

I've already removed the output flange and old seal, but am curious as to what is the best way to drive in the new seal. Would a generic seal driver from the local auto parts store fit around the output shaft to drive the seal in? Or is there a better method people used to drive it in evenly so it does not go in sideways?

Car is an '89 535iA.

Cheers,

IF the old seal is in decent condition you can use that, or a socket that fits the metal part exactly.

In case the groves are too deep, you could try speedy sleeves, see here the info

A piece of plywood with a cutout? I don't use it because I can get a socket from my 3/4" drive socket set made in you know where.

Looks like I may go the wood route. I'm having my friend who's a woodworker make me a wooden ring that will fit around the output shaft and can be used to evenly distribute pressure on the seal when lightly hammered on!

Thanks for the suggestions, everyone.

good route, try to make sure the seal is drifted in evenly. I use a coating of silicone on the outside of the seal for added measure.

I installed the output seal using a socket extension and light taps from a hammer. This method requires some care, but makes it fairly easy to drive the seal in evenly if you make sure to position the socket extension on the edge of the seal and leave part of the blunt end hanging past it. When you drive it in all the way, you naturally stop at the lip of the rear housing. If you can make a proper seal installation tool/ring, do so. In a pinch, a socket extension won't damage the seal and works well enough to drive it in. Just my $.02
