Got in 3 full days of work this weekend. I have had this truck for 10 years, and never had the starter off. And it never failed to start either, so somehow the starter was broken but still worked. There was often a chirping sound from the trans area for years, which I feared was a cracked flex plate, but now I realize was the chunk rubbing against the starter gear.

What is this seal called where the cv shaft goes through the knuckle? I searched ebay on every word combo I could think of, but found nothing specifically for the cv shaft seal.

I think this is what you're looking for: https://www.napaonline.com/en/p/OSN27SS3344?impressionRank=41. I also seem to recall seeing that an H2 hummer used a seal that was interchangeable but was of a superior design, but I don't have the details.

Thanks, that does look like it. I will hit a napa tomorrow.

Does anyone know what this connector is for on the back of my power steering pump?

EVO, gives you a high/low assist when it works right.

Ok cool, is it supplying 12v, or is it reporting back to the ecm?

It doesn't report to the PCM. It shares a module with the keyless entry. Not sure how much juice goes through it.

 

[Scottm]

That's weird, I don't have keyless entry. What does it do?

When I changed my PS pump I got one without the EVO, tapped this connector up and out of the way. Didn’t notice any difference in steering without EVO.
