I am at the no return stage where I have cut the old boot off (it was had it anyway) and unbolted the rack both ends and the oil lines. Do I undo it from the colum, the are two cap srews by the look behind the vacuum brake servo under and over the alloy housing for the colum. These look like they would release the whole rack which would come out like an odd tee shape, one with a very short leg. Then I could see that the boot would slip over the rack easily.
I am replacing the steering rack boot on my Audi 100 Avanti 2.3. Any suggestions on 1994 Audi 100
Its hard to give instructions without illustrations. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
Job done, funnily, the Audi dealers here don't list a seal replacement kit for the rack, one specialized tool would be needed to replace the shaft seal but everything else just requires only standard hand tools. Undo the tie rods mounted on the rack, bend back the locking plates with a hammer and screw driver, 19mm spanner and the unit comes away from the rack.Undo the knuckle joint from the steering column to the spline (by the brake pedal) 13mm spanners. Right hand drive vehicles, two 13mm spanner bolts right end of rack, 1 x 13mm spanner left side, rack pulls out, when away from the brake vacuum chamber undo the two hydraulic lines that are flexible, 19mm spanner. Take left front wheel off, wriggle the unit around until the end can be pushed through hole next to the suspension, end down until the opposite end can be pulled out through the engine bay. Whaloo! reverse the procedure once the boot is replaced remembering that every pipe, electrical connection and fitting in the engine bay, is now brittle from age and leaning on them cracks them-bugger!!!!!!
