I am replacing my ps pump in my 2005 yukon XL next week. I can't stand the noise it is making, albeit you can only hear it in the cab. I don't think that I have ever done one. (at least that I can remember). Any tips? I am going to rent the pully puller from autozone so I can pull the pully off of the old one and press it onto the new one. Any tips/suggestions before I start this job? The lines are just clamped hoses so no worry about getting the lines started without cross threading. I bought an AC delco with reservoir, so I don't have to deal with switching that over. I have read that after install I should fill it and soin it by hand a few times to prime it. Any help is appreciated! Thanks.
