Hi guys, long time since i had the mini upto motorway speeds, but did today. 

 

Shes got a nasty shudder at 65+ like steering wheel and front end, its shaking my calves. Steering wheel bounced left and right maybe 1" no real bias in which way it wants to bounce seems to go from left to right and remains straight.

 

• Wheel bearing have no play 
• ball joints have no play
• both U bolts still present and tight 
• tyre pressures all good
• wheels balanced 

 

Going to try swap front for rear.

 

 

I saw something about checking steering bushes, where are these?

Check the holes in the wheels are actually round. I have a set of 10 inch Rostyle wheels that are scrap because the stud holes have been ovalled

When were the wheels balanced?

[whistler]

Check that the wheels have the same PCD as the studs. I have found wheels with a PCD of 100mm fitted onto Minis which should generally be 101.5mm (4 inches). This can cause wheel wobble as well as damaging the wheels/studs.

Thanks for replies guys 

Sorry for delay. Just swapped the wheel that looked bucked for a spare. Still have the shake. Think ill swap rear for front

They are minilite type alloys so assuming its the imperial not metric PCD

check the pitman arms it may be one of the bolts broken

Checked bothsides they were fine both bolts felt more like studs then bolts but still solid

LOL. I assume you mean the steering arms on each hub.
Mini has a steering rack. It does not have a pitman arm!

Try track rod ends, see if there is any play

[A-Cell]

Get the wheels balanced again. Maybe you list a wheel weight or weights. Or they were never done properly before.

[phillrulz]

Right, what  was behind is now infront and what was infront is now behind. 

 

With a quick 90mph blast up the A40.... I Can happily say not a single steering wheel wobble.

 

Looks like i have a bad alloy. Guessing driver side as i had previously swapped passenger side as i stuck the car in 1st on axle stands and let the wheel spin passengers side looked more wobbly. 

 

 

When my local tyre shop moves premises ill take the rear allows over for an inspection, weird thing is they didnt look too bad. 

 

Weird how the bloke balanced them today one was showing like 10/55 and one like 20/65.

First thing i checked, as for prev MOT had to change steering rack gators i had track rod ends off. Both good issue solved

I got them balanced today as i had the vibration, it didnt help at all. After swapping front wheels for rear its done so an Alloy is buggered will get it looked at by the guys i trust.

Glad you narrowed it down. Out of round wheel!

Must be, i checked both by letting the wheels idle around in first, however passenger side looked worse.... owell no more death shakes for me 

Cheers for helping

Never assume where a Mini is concerned.
