[20v] Steering Rack R&R experience?

[Peter Schulz]

Thanks Bernie, but this is for a Type 89 Sedan (1991 90q20v)

Even though the rack is similar,there's alot less room to work in a type 89 than a Type 44...

I need some BTDTs as to what tools to use ( think I will need a curved 17mm box wrench,perhaps a ratcheting box to get the two main 17mm mounting bolts under the rack), probably similar for the high and low pressure lines.

Also, what needs to be removed to pull the rack (tie rods are a given), stuff on back of head - breather etc TB etc...

There is a wiring harness in the way, pass side wheel well. It can be forced aside to make room for rack exiting. Rack overhaul is the easy part. These ZF racks are bullet proof, EXCEPTING for the high pressure rod seal. Last time I redesigned this seal, replacing the (cheap) hard plastic seal with an elastormeric quad ring backed up with a nylon back up ring. Still no leaks at 100K. Bentleys are not much help but the 5K a little better than the 200 version. Ask specifics as you go.
