Alrighty then, I will wait till I can get some negative vacuum and see what happens.

Ok, have Turbo, exhaust, intake pulled back off. Have some welding to do on the exhaust, noticed a couple pin holes also need to trim clamps and some other misc odds and ends to clean up.

So I figured since I was working on the seat belts I would go ahead and check rear wheel bearings. Don't remember grease being on the splines. Normal? I'll clean and pack the bearings, new seals and such. Was just wondering if that was norm, been awhile since I pulled them.

When I grabbed the spline it felt a little rough in rotation, didn't sound good either. Took it apart, bearing wasn't that old just started to deteriorate, plenty of grease still packed inside.
The o-ring between the outer bearing inner race and the outer thrust spacer should be keeping the grease inside. Maybe the bearing starting to fail allowed enough wobble in there to let the o-ring leak. At least the grease on the splines makes it MUCH easier to remove the drum than if dry and rusty. I prefer to use anti-sieze for that.

The inner bearing was the one to fail, no wobble just could feel and hear it when I turned by hand, sounded dry but it was still packed with grease. I am going to clean it up and see where the bad spot is at. The only O ring i had was the large one, no small one installed, hmm.
I am stoked today, not because some team won the Super Bowl but because I felt the boost of a Turbo in the buggy today. I need to do some jetting but AFR was in the 9 range at 5lbs which is all I wanted to do right now. Wasn't sure how much lag I was going to have but it was fairly responsive, I was smiling ear to ear for sure.
The turbo is not building enough steam (for me) so started trying to figure out why. I have a couple very small holes inside of the exhaust. Now to figure how to get to it. I hung the turbo on some wires and took it out. See what I come up with this weekend . Not exciting but the end result should help the excitement factor.

Little rod going across was a brace, now it is in the way.

When I was running way rich noticed the pin leak, finally took it off and did something about it. It was not easy getting in there, I used flux core wire with the tip shield off.
Before, really two small pin holes in the prievious repair.

Doesn't look pretty but hopefully will seal it up without being brittle.

Leather are your rear shocks any better? Also are you more comfortable working on them now?

A lot better Ed, thanks for all of your guidance on that. We took a couple good bounces and the butt stayed down vice jumping up in the air. Feel a lot better about working on them, not the witchcraft they used to be.
