Default Replacing Needle Bearings

I'm at the point where I just have to instal the grease nipple and pump the grease through to get the bearing out. I would like to ask 2 questions if I may?

1. I see a whilte type of grease on willwren'* "replacing needle bearings" Tech guide, is that lithium grease or can another grease be substituted?
2. When it states to" clean out (all of it, use solvent)" meaning the grease, can I use brake fluid or should I use another type of solvent?

Thanks

Any grease you like. It'* just a hydraulic media to force the bearing out under pressure. You could use air if you had a way to do it.

Brake cleaner would be a good solvent to clean the grease out with. Just don't get any on your rotors.

Come to think of it, I can't remember what I used to clean the rotors.......what would happen if you did use solvents on the rotors?

Bad stuff.

You should have used Castrol Super Clean like I suggested.

Does anyone know what would happen if you did use solvents on the rotors?

Yes, we know very well. Certain solvents will remove the epoxy coating on the rotors and you'll lose between 1 and 3 PSI of boost, and have to replace your rotor assembly. Even if it doesn't come off right away, it might later under operation.

Awwww, crap! Thanks once again for sharing your expertise although that'* not what I wanted to hear. Unfortunately I don't have new rotors in the budget so I'll have to let them soak in soap and water for the next couple of days before putting things back together again. I'm not sure what losing 1-3 psi of boost means. I know maximum psi is 10. I assume that will affect performance, but will it also affect fuel economy and, if so, how?

I got the car back together again and to my surprise................................it started. I have a couple extra nuts and bolts left over so I didn't take it around the block or rev it up. I'm going to have to give it a once over to figure out where the extra parts go.

Just thought I would keep you guys and gals in the loop...............if you care that is.
