I have a rear pinion seal that is leaking on my '07 Tacoma. I had originaly ordered a "generic" seal and after I put it in it IMMEDIATELY started leaking on the lift! Never put the truck back on the ground and it started leaking. I then ordered an OEM Toyota seal and before I installed it I slipped it over the flange base just to see how tight it seals around the flange - it's not really tight al all. You can see a little daylight between the seal and the flange base. The generic one is the same. Have I got the wrong seal? I'm not sure how in the hell oil is NOT supposed to leak between the flange and seal!
