Hey guys, Finally got around to chasing a Power Steering leak that occurred during the last track day. It's seeping out from the housing up around where the pinion assembly joins the steering linkage. Now I know there is a whole bunch of seals in the housing, question is can I replace the seals in the housing without pulling the rack? Also I couldn't find a seal kit from coz, but rebuilt racks are only $300 plus shipping of course. Insights would be good...cheers Cheers
Maybe try pming chrispy as he's had these racks apart. He should be able to tell you exactly how to tackle it. However 300 for a rebuilt unit is pretty good.
Can be done in car easily. Three bolts hold the pinion housing to the rack, remove those, the 2 pipes and the steering shaft. Pull the pinion housing off, knock the seal and roller bearing out of it carefully because sourcing another roller bearing is not easy. Take seal to bearing shop, I have not found a seal with the exact dimensions but have found one 2mm wider and works fine. Clean both pinion and housing very well, refit seal and bearing, reassemble.
Courtesy Parts to the rescue Costing me about $30 all up for every possible seal, o-ring and bearing in the vacintiy of that pinion assembly I might even do a write up when I get around to it...probably not though.
What's to write up? Whenever something is disassembled due to a leak it is routine to replace all seals and gaskets. All of them, every single one.
