Hello I have 99 sport has small Leak rear main seal. Is it huge job ? I know pull motor or tranny. Got quote for a grand. Love the truck.

Thanks

David.

Honestly, I don't think it is. I haven't changed it yet, but it doesn't look to hard. Just get the right tools and definitely a Motorcraft rear main seal. I have heard bad things about using off brand seals
To remove the old seal the only way I've seen is with a couple of old screws or a small pick like from harbor freight.
Just be very careful that you don't scratch the crank as that will cause the new seal to not work properly.

We pulled our engine to replace the timing chain cassettes and chains. Figured we might as well replace the rear main seal while the engine was out.
Good luck!
