OOOright, I got a problem with a mini that pulls to one side only on deceleration. The car will drag to the left under deceleration, and slightly less so when cruising. When I accelerate, even only slightly, the car will track straight and true. It doesn't seem to cause any undue wear on my tyres though to give it away.

I've checked all the bushes (all in good nick it seems, eurathane type), and all the ball joints are spot on and brand new this weekend. Ther's no apparent play in the steering rack or joints. The car squats a little on the front hydro bags (one finger width gap to the wheel) which may not help the issue, I'm not sure.

Can anyone tell me what's going on, and what I should check?

When you say decelleration you mean under braking? or just no pedal and in neutral from speed?

I haven't noticed whether it does it under braking, I'll have a look today.

I mean by deceleration when I lift my foot off the pedal, even only lightly or when I'm just cruising. When I add some power it straightens up and I can lift my hand off the wheel and still go straight.

Grabbing caliper?

wheel alignment?



tyre pressure?

running over pedestrians?

I had a "banana in the rack" or steering arm when I had the same symptoms.

I am guessing your problem is steering related.

Callipers are fine, I checked for that. Tyre pressures are good. I haven't done the wheel alignment yet(although prolly obvious) because it only does it while decelerating but is good when speeding up. Like something is moving.

I'm not a geometry guru, but what do you mean by banana rack? The whole thing is bent? I can't help but think that something is shifting under load.

Trailing arms might have gone and be letting one of your rears wobble...

Yeah, back when I knew nothing about Minis, this is how my mechanic described it to me as.

I think maybe a steering arm was bent, or maybe the column?
Not too sure.

But your symptoms are definitely the same as what mine were.
And it got worse.
A LOT worse, one night, until I had to pretty much limp it home from fear of spearing off into a fence or something

checked those too, I rebuilt them a little while back and they're still beaut.



The problem's stabilised after a little while and haven't gotten any worse. I wonder if a wheel alignment will be a waste of time if it only does one thing accelerating and then another decelerating?

Yeah I had that problem once, it was the end ball joint on the rack, it had undone itself and the wheel was trying to point elsewhere - pretty scary stuff.
