[TR] TR4 rear pinion seal replacement

[Brad Kahler]

Unfortunately the axle is in the car and I have no plans on taking it
out.  I've got a seal removal tool and if that doesn't work I'll try
screws and then dynamite :)

Thanks for the info on the preload.  Should be interesting trying to
keep track of turns coming off.
