1992 Mini Cooper 1275 - Steering Noises - Kildrummy

I am getting some nasty clunking noises when driving very slowly and turning the steering e.g. parking. There is a bit of play in the steering but I guess what I am hearing is the noise of a worn steering rack. Maybe some one could confirm that for me.

My main concern is that I have to drive about 20 miles home on city and country roads would any body know if its safe to make a journey with this problem. The noise only started today although I have been aware of play in the steering for some time.

Appreciate any comments

Could be the retaining bushes on the rack...

I would recommend you have it checked asap by a competent garage..

Thanks for that,

Would it be ok to drive with that problem? Is that something that can be replaced rather than the whole rack??

Don,

I would post your query on a Mini forum to see if they can hep with advice. From what I can remember of a Mini over 30 years ago the symtoms you describe could be worn CV joints, I think they were sometimes called spider joints, the inner ones anyway. Driving at slow speed on full lock listening for clicking / clunking as you describe was a test to identify worn joints.

Regards,

It does sound like CV joints.

If the car has the solid, (non hydroelastic) suspension check out worn knuckle joints on the upper suspension arm.

Q.

1992 Mini Cooper 1275 - Steering Noises - MrEckerslikefromRamsbottom

Does it feel as if the whole steering rack is moving slightly from side to side? Everything on the old Mini is so simple. The steering rack is held in place by two simple 'U'- bolts. These 'U'- bolts should have a plastic pad which the two threaded legs go through and this helps to hold the steering rack in place. Just lift the carpets in the footwell and try tightening the two nuts each side which tighten the 'U'- bolts. If they are indeed a bit loose, it could be that a previous owner has had the rack out and omitted to replace the plastic pads. (I had a second hand Mini where the rack came loose because of this).

As Quicksilver points out,the knuckle joint on the end of the suspension trumpet (rubber cone suspension), or hydrolastic unit, can wear through its nylon cup and start to grind away at the upper suspension arm. Just a matter of using a wind-in compressor tool for the rubber cone and changing the knuckle joint. If the seating in the upper arm is badly worn away, a bit of plastic padding will support the new knuckle joint cup.

Ball joints wear out. They need constant maintenance. We used to re-shim them regularly. I know one lad who used to take down some of the shims from his Quinton-Hazell ball joint kit on an oil-stone to get the the thickness 'just right! Always use a waterproof grease in your grease-gun to lubricate not only the ball joints but everything else, especially the rear radius arm pivots. And use the grease gun regularly! Don't use Castrol MS grease as this will emulsify.

One other thing - are the dampers (shockers) OK? They can clunk if they're worn out.

Er.. Now that I've had a think, check your track-rod ends. They used to wear out quickly on the Mini and its one of the few things which doesn't have a grease nipple. Wear here can cause play in the steering.

By 'waterproof grease' in the above post, I mean the vile-smelling dark brown stuff that's marketed as 'boat-trailer hub grease'. You can get a pot from Indespension if you live near Bolton.

If you have to change the track rod ends or do anything on the steering, I recommend that you try to find a 'Paddy Hopkirk Tracking Gauge' as being the easiest way to set the tracking correctly. One-eighth to three-sixteenths toe-out was it, or have I lost the plot after all these years?

Thanks to everyone for your suggestions and help. I managed to drive home on Friday but it was a bit scary. The play on the steering got worse in the 20 mile journey and I had to take it real easy to keep the old thing on my side of the road.

The noise I was getting was mainly when parking. You may remember how heavy the steering can be if any of you have a car with no power steering, as I was turning the steering wheel to reverse into a parking space I got this loud knock and the steering wheel appeared to move at the same time

I am thinking the issue of the steering rack being slack might be the answer. The car has been totally dismantled and restored fairly recently (not by me) and I have found several things that were not connected or wired up etc. so it's possible that the previous owner would have had the steering rack off during the resto. the track rod ends appear to be ok but I will be having a look at the bolts retaining the steering rack when I get home from work tonight.

Thanks again

Just one last thing to check which I should have mentioned..

Speaking to my friend in Poynton on the 'phone last night - he's got a back garden full of Minis and Mini derivatives including a Midas.. He reminded me about the splines where the steering column fixes with a pinch-screw to the splined shaft of the rack which sticks up through the floor - this won't come completely loose because the pinch-screw fits into a groove in the steering racks splined shaft, but it has been known that if the pinch screw is loose, the splines will wear away, so it's something to check.

Cheers, I take it that should be visible from inside the car?

1992 Mini Cooper 1275 - Steering Noises - MrEckerslikefromRamsbottom

Yes, like the 'U' bolt nuts, just need to get your head down in the footwell and look right at the bottom of the steering column. The steering column is removed by loosening the 'U' bolt nuts, releasing the shear-bolt (which the previous owner should have replaced with an ordinary bolt) from the bracket beneath the dashboard, then taking out the pinch screw down at the bottom of the steering column and pulling the steering column off the splines. Simple.Ensure that the pinch screw is tight.

If the 'U' bolt nuts are indeed loose (I can think of nothing else) , replace them with Nylock nuts with wide penny washers under them. Replace the nuts one at a time, of course.. Take 'em both off and the 'U' bolt will dissapear down into the subframe and you're going to have a bit of bother to get it back in!

I think I have found the problem. The pinch bolt appeared to be fairly tight but when I turned the steering wheel and touched the steering rack part below the pinch bolt it didn't move much at all but the steering column did. I tightened up the pitch bolt and it appears to have fixed the problem but I think it could tighten a bit more but don't want to overdo it. I looked in my Haynes manual for a torque wrench setting but nothing listed for a pinch bolt. Tomorrow I will check the U-bolts as well.

Appreciate your help.

Not many of us could afford a torque wrench in those days! If it's bl***y tight and there's still a bit of movement, then the splines are worn! However, to make sure that it's lined up ok, slacken off the 'U' bolt nuts first, then the splined bit sticking up can be moved a bit to be perfectly in line with the steering column, then tighten the pinch screw and lastly tighten the 'U' bolt nuts.

Thanks again for your help. I will check it out tomorrow night.
