Mini Steering Rack


Craig said:

Listers,
I've just acquired a second mini (thanks Matt), and was wondering. The steering rack on Floyd is making a little noise...sounds like it is moving side to side while the wheels don't move...is the rack of better spec than a standard mini?

Floyd is a 66 Cooper S MkI and the second mini is a 1966 Mini Delux. Any ideas?

Hi,
the racks are identical. There's been a change in design in 1969 IIRC. From then on the turning circle is smaller, but in order to fit one of these you also need the steering arms.

G'day Craig,
Before you go too far with deciding to change racks, get someone who knows mini steering racks to check which one it is. There are two Mk 1 types and the Mk 2. They all have slightly different damper cover plates. If it is not the original rack and has been replaced at some time, it may be a Mk 1 rack which used a pair of dished diaphragm washers as springs instead of a proper coil spring. These often break up and allow the rack to slop a little giving the symptoms you describe. I have only recently had my spare rack overhauled to replace my sloppy one, and when we had the car on the hoist to start the changeover, the mechanic said that he would remove the plate from the existing rack to check the spring washers first. This proved to be the problem and a dollars worth of spring washers later, the steering was back to normal and I now have a reconditioned rack spare!

ALL (standard) Oz cars use the early Mk I style rack. If you order a rack from OS make this clear to the supplier. That said, the later (UK MkII onwards) rack is a HUGE improvement - tight parking is much easier with 3 feet chopped out of the turning circle.

Just remember, the matching late model steering arms (identifiable by their little "ears") must be sourced OS as well. As a set they will bolt straight into an Oz Mini.

Cheers, Ian
