steering wheel shake at 60mph.

Post by Tom17 » 01/08/11 17:23

Hi

New to here and also to MR2 ownership. I recently bought a 1989 Mk1 having been thinking about it for the last few years and decided to have a go.

On the test drive it had a slight shake on the steering wheel at 60mph which went at about 70mph. I got a bit of money off for that and with no other mechanical problems decided to buy it. Just looking into what the probelm is now.

It has had 4 new tyres about 3000 miles ago(although that was 3 years!) and all the weights appear on them. There does not appear to be any play in the bushes although they don't look new, however there is a small amount of play in the steering rack both ends. This is only noticeable when the car is jacked up and force is applied to the road wheel. There does not appear to be much play at when the steering wheel is turned.

Can the rack arms be replaced or will this need to be a new rack? It doesn't look that difficult to do as there appears reasonable access.

The brakes look old, although appear to be wearing evenly. I may replace these anyway as they need it soon.

Just wondering if anybody has any thoughts on what else this may be, before I decide to go and spend a bit of cash on new bits and pieces!

Oh and i'm also after a good cover for it, anybody have any ideas/reccommendations?

First thing to check is to make sure the wheels have been balanced properly. :th:

+1 i had this i assumed all was ok as the garage putting on the new tyres had put shiny new weights on......

But they had not cleaned the surface properly and they were lifting off at speed

I was thinking ball joints etc, and thats all it was balance weights, i did replace the track rod ends as they had paly in them but as i say once wheels rebalanced all hunk dory

Check the brakes arent binding, doesnt have to be enough for them to overheat. Just jack up and spin the wheels by hand see how easily they rotate.
There is no "it cant be done" only "I cant do it!"

Thanks, i'll check the double check the wheel's first. I don't think it's the brakes as both spin no problem.

only 3000 miles but 3 years means that it has been sat for long periods.
This may have caused a bit of a flat spot in the tyre and that would manifest itsself like an unbalanced tyre. Especially if the tyre had lost some air before being put up for sale.

Wheel shake at 50-60 is 90% caused by unbalnaced wheel / tyre. Get them checked 1st before spending to much on anything esle.
Take it the 2 has standard wheels on it that fit properly - if none standard check that they have spoggot rings in place to marry up the wheel bore to the hub diameter. missing these on after market wheels also gives you wheel shake / wobble. If standard wheels disreguard the above.

I do that too, it's just a bit disconcerting when going through the 60 barrier! I'll look at getting the wheels done. I've taken it off the road for a little while as there a few other little bits I want to do to it first. Hopeully it will be the wheels/tyres and it will be sorted.
