Any difference in steering racks?

cbr1100xx · 16th August 2018, 08:19

Hi
I have a chance of a brand new rack for the zt but the guy selling it is saying it's for a late model only.
I thought the racks were the same , can any one enlighten me.

There are two versions according to this: https://rimmerbros.com/Item--i-GRID002020

- but as to how they differ, I've no idea. I seem to remember the ZT uses a higher ratio than the 75.

I seem to remember reading a post by one of the many oracles that the later rack had a tighter turning circle , but I can't find the post.
Would that make a difference in fitting?

I would expect the actual mounting/fitting would be the same since all the bodyshells are the same. But get confirmation before committing.
Can't think the turning circle would differ, I have the gear ratios in mind.

The ZT had a different steering ratio to be more responsive. (ie. less steering wheel turns from lock to lock).

I am pretty certain that on the Mark 2 Rover 75s they standardised the rack across the range, so the later Rover 75s were fitted with the same rack as a ZT

Thanks for the confirmation, which tallies with the Rimmer listings.

So I should be ok using it on a 03 zt , the part number is 000220

Supervinnie40 · 17th August 2018, 09:53

I changed my steering rack last winter. The 75 has a steering ratio of 3.7 (from memory....) which means 3.7 turns to the left or right. The ZT ones have a ratio of 3.2 I believe. It has been a while.
Both racks fit, and both would fit. But be a bit careful, I bought a brand new one, still in the packaging that came from France. It was supposed to be a real Rover one that simply hadn't sold yet (in the last 15 years orso...). In the end I had nothing but problems with it and a garage that reconditions these racks confirmed that it was actually a very poor reconditioned steerick rack.
I paid twice the purchase price to get it properly reconditioned.

I hope you have an honest seller, but I'd recommend to be very careful.

Fitting is a bit of a pain in the rearside. Its not difficult, its just not easy to get in there.

I have found this old thread.

According to post number 3, lock to lock, it is 3.2 turns for the earlier Rover 75 and 2.95 for the MG ZT.

Cheers guys very helpful.
On the seller front it is a friend of my brother who used to have a zt and he brought it new but never fitted it , and he has a few other bits sitting in his shed so will find out what's knocking about next week
