I changed the rack on my 940T. The original was a Koyo that worked well but had a loose inner tie rod end. With 255,000 I decided to change things. I had an excellent low miles TRW replacement I had gotten at PnP and put in my 740 that was wrecked so I saved it. Research indicated that the only difference, if changing everything out to the outer tie rod ends, was the high pressure hose. I ordered a hose from Rock Auto using the TRW/Cam listing. It was a perfect fit. However, the return hose up to the reservoir was different slightly where it mounts to the rack, the bend was different. Too late to hit PnP for another, my friend came up with a way to bend it just a little so it went in fine. But if doing this yourself I'd say get the hoses also.
The high pressure hose is a toughie to get out of the pump. Very hard, my flare nut wrench was opening slightly and starting to round off the corners of the fitting. Taking the pump out made things much easier, a mech's tip was to put a vise grip on the flare wrench so it can't open, and then tightening it also on the bench worked out well also. Getting the angle of the hose right was not too hard. Then, thread the hose into the hole in the crossmember to the rack, and lift the pump and reinstall. I used Dexron 6, one quart did it. It took a while to bleed the air off but seems good now.
The car now has excellent direction and steering. Tight, light, good sense of the road.
With all the high miles most of our cars have, I hope this helps someone.
