power steering box input shaft seal

[Kain]

treid to get a seal for the input on the gear box. found the hard way that there is a box from a p20 van on it.
had to run the numbers on the gear box to get the right seals but hopefully that fixed the leak.................

So far so good no more leaking power steering fluid

What is so unique about a p chassis steering box?

 

[Kain]

The input shaft is bigger
The blazer is a 3/4 shaft the vans is 13/16 or something like that
I guess heavy duty system
Just a guess though

I just picked mine up for my p30. The input shaft and the knuckles are huge.

If you ever pull the wheel on the p30 the steering shaft will slip down. Is not horrible, but putting the wheel back on the threads won't reach. I normally had a helper push up from under the truck, or blocked it up with cribbing and a floor jack.
I did hundreds of turn signal switch repairs/replacement on these. 1980 to 2010 models.
