Steering Gear Replacement what else to replace

Tcrate · 10-13-2011, 10:37 AM

Well got home this weekend and my wife had driven the Porsche. Started the car , the pump was whining and the fluid was dripping on the ground. Seals on the steering rack, both ends, were shot. I added fluid and the pump quit whining but definitely the steering rack is shot.
So while I am replacing the rack I am looking for feedback from others who have done this job on what else you have replaced. My plan is the following:

Steering gear - Buying a rebuilt unit.
new boots (bellows)
2 rubber bushings
reservoir
Reservoir to pump hose
(this had rubbed against pump previously and I rigged a regular piece of hose. Would like to go back to original with the proper routing)

Pressure line (showed on the one rubber connection it was wet with fluid. Could not tell where the leak was or if it was overspray but I am not taking chances.

Outer Tie rod ends. The originals are not bad just figured while I was there.
Using original inner tie rod ends.

So for the most part there are two other hoses I am not replacing. Is it worth the money to replace those. They are not cheap......

Has anyone else done this job and what did you replace.

Why change the reservior? it can be cleaned,I wouldn't replace the hoses with genuine on principle that they are way over priced and were rubbish any way.
Get some good quality flexible power steering from a hydraulic hose supplier and remember to fit the protective spiral rap on it ,save a heap of money then you can replace your tie rod ends and still have money left over for fluid,etc
Get the pump stripped and cleaned I don't think Porsche make a seal kit but from memory its only a few o-rings again get o-rings from hydraulic parts supplier as well.
Don't buy the cheapest rebuilt rack as quality of repair generally reflects in the price you pay,ask around on here for good suppliers.

A while ago I resealed both my PS rack (leaking badly) and PS pump - seal kits purchased from Rennbay as I remember. Less than 100. total in parts. Nothing too complicated...and both rack and pump continue to work great.
