When replacing the inner tie rod ends the manual says to hold the steering rack (and entirely remove the steering rack before, so you can hold it) in order to take off the inner tie rod ends so that you don't torque on the gearbox and potentially damage the gearbox.
Is it necessary to remove the steering rack to do this job? Or, is there a way around this? Will it really damage the steering gearbox? Could I try and hold it in place with it still in the car while I remove the tie rods?
I have only changed those things out of the car, sometimes they use thread lock on the threads and so can be very tight to get off. I always wrap the shaft in a rag and put in a vise. I find its the power steering lines that are a bugger to get off and then back on tight. Just be thankful it's not an auto as there is less room for your hands to reach in there.
