Is it not something that can be done yourself? I only ask as I don't know.

cheers but its nothing with the bushes.

I wouldnt recommend the bushes anyway, the bolt shaft is 8mm and the bore of the bush is 10.4mm so there is a lot of play.

I found this out after i had bought a set.

i also really do not like the idea of solid metal to metal contact on the other support especially as there will be movement in the rack.

i need a rack refurb as the shuttle valve assy inside is worn and produces a knocking sound when changing direction.

as an update and closure... i replaced the figs solid bushes back to the original rubber bushes, and the knock sounds reduced by at least 50% because of the huge gap between the bolt and the bush... figs just copied the sizes from the original bush without checking the bolt size :confused1:

i replaced the rack with a replacement from a breakers and the knocking sound is gone confirming wear on the rack.... it took me a total of 2 hours including putting the car on and off the ramp , cleaning up and packing my tools away.

Next time someones car is up on a ramp it would be a good idea to coat the rack in moly grease easpecially the rack teeth to help reduce any wear. no need to use metal clips on the gaiters, big ty-wraps work just as well.

Sparkystav thanks for the info rob,

i still have the old rack sitting in the boot, but the only way to have no play beween the rack bolts and the bushings is to make a split collar that goes on the bolt shaft. the thread is 9mm but the shaft is 8mm, confirmed with a digital caliper.

Reading the workshop manual it says the rack teeth should be coated in either moly grease or steering fluid.

i used 60% moly grease and put a thick layer on and worked it into the teeth, this should help with any wear.

be aware that many companies that offer refurb racks have a note in the small print that is the racks are worn they will retain the deposit. so you end up paying about £400 for a rack. :thumbdown:

just get one from a low mileage car and you should be fine.

worst case you can get a NEW rack from the US quite cheaply and by looks of it you can swap over the servo housing to have it pointing the right way for the column.. TBC though !

I have scrapped the old steering rack and knocked the figs solid bushes out.

i found a solution for the gap.. put a piece of shrink wrap tube on the shaft of the bolt and then shrink it.

Perfect fit between the bush and bolt shaft !

ill have the bushes for sale in the next days.
