The truck seal does work in the car housing. It puts the rubber lip in a different location deeper in the housing. As long as it's not too deep it will work with no problems. Some of them are made too deep and will cause problems. You just have to be sure that you check it when you install it and be sure that the rubber is not making contact with the bearing.

Agreed, Fred. I post this photo solely for future reference.

Tom,
How did you make out at PSMCDR?

I've ordered a new pinion yoke, the Ratech seal mentioned above, and a new pinion nut. Hopefully this will solve this issue.
I did tape a paper shop towel to the bottom of the rear end and take the car to the Pure Stock Muscle Car Race. Changed the shop towel out once while I was there, but it wasn't leaking very much. Someone spoke to me from this list, but I was in a hurry, seems like I was always in hurry while I was there, and I didn't get his name - I would like to thank him for taking the time speak to me.
The car did well for what it is - and it's first time at the track. I got a best of 13.90 and 99 mph. I won about half of the races i had - but I lost my shootout. Over all I had a lot of fun and learned a lot.
Now after I get the pinion seal leak solved - I got to do something to stop the wheel hop. The wheel hop really affected me trying to do a burnout, and how I could leave the starting line. So, more to do yet.

Are you using thread sealer or RTV in the splines in the yoke when you install it? If you aren't then you probably have a leak coming through the splines. You always have to seal the splines, but do not put the sealer on the pinion. Always put it in the yoke. If you put it on the pinion then you will push the sealer into the outer bearing when you install the yoke.

Thanks Freddie - yes the mechanic doing the work for me has been putting thread sealer on the splines. I feel the problem is just that the yokes are worn where the seal rides. Also, in looking to see just where the fluid is coming from, the area around the pinion nut is dry. The fluid is leaking off the bottom of the dust cover on the yoke.

----Hop stop bars will kill the hop. They will change the instant center. You won't even know they are there most of the time, but no more hop. Research it so you are comfortable with the idea!....Bill S

13.90’s is great considering it was your first time out with the car and it isn’t sorted!

Does your car have red lines and small hub caps?

If so we shook hands and talked for a couple minutes at your car. I thought your car might have been one that Dan Vasic restored as the theme was so similar and they both ended up with dark blue license plates BC and Connecticut?

Thanks Ryan, yes that was/is my car and I do remember talking to you. Thanks for spending a minute or two to speak with me - I appreciate more than people know.
Bill S. (Old Red Alert) - I have been looking at the Stop-Hop bars. Some also call them traction bars. Some say that they work but make the car ride harsh. It looks like I will probably be getting a set after I get the pinion seal leak fixed. Thanks for your input on this issue - I value it more than a lot of the ads.
