Sierra steering wheel boss removal
BangedupTiger - 9/5/20 at 10:15 PM

Has anyone got a photo of what the steering column looks like without a steering wheel or boss attached.

The boss on my tiger is completely stuck and I canít work out how to get it off. Usually I end up wrecking things when it turns out to be a simple fix.

Itís currently got a billet aluminium boss. Possibly made by the previous owner. Iíll try and get some photos up.

The centre nut doesn't appear to be doing much. I original thought the 3 studs were holding the boss on, but even once the nuts are removed its rock solid.

I assume the boss is splined? but doesn't look like it from inside as far as I can see.


Any ideas on the best way to remove it?

usually its a splined shaft, plus a taper fit too. the nut is there to ensure it doesn't move. you need a hub puller of some form. (hint put central nut back on loosely so you can't mangle the threads.)

What I mean is the centre of the aluminium boss just appears to have a hole in it that the column comes through. It doesnít appear the centre hole is actually connected to the splines.

It looks more like the 3 studs are whatís holding the boss in place.

Are those 3 studs normal on a standard Sierra column?

I would replace the steering wheel, slacken the center bolt a couple of turns then pull the steering wheel towards you while giving the bolt a sharp tap with a hammer. There isnít a spline , itís a hexagon

IIRC you might also have to have the key in the ignition and the steering unlocked.

If it's a Ford Sierra steering column that's my memory as well, a hexagon, not a spline.

As advised slacken the nut a few turns and sit in the car a pull the steering wheel towards you. It should come off without too much effort.

Looks like there is a boss on the column and aluminium quick release on that boss.

Centre bold should remove whole assembly, but only if the steering lock is disengaged.

As stated by Keith, make sure the key is in and the steering lock is off before trying to remove. Normally pressure on the back of the steering wheel on one side and a gentle tap on the back of the other with your hand is enough to get it off when the steering lock is disengaged.

Here's you go. As others have said it's hexagonal.

Thanks guys. Has anyone got a photo of the column without the Aluminium spacer on but with the black metal back still in place.

There is no way its pulling off by hand. And no where to really attach hub puller, I still don't think the hub puller would remove anyway.

Only options I can see at the minute is cut it off with an angle grinder (hence need the photo to see where I can cut) or replace the column.

Anyone got a spare column available?

This is starting to make sense to me now. I thought the black part was part of the column. But from the photo below I now think is a Mountney part. It seems the 3 studs are part off the Mountney black boss and the Aluminium is just something the builder made as a spacer.

So if I bolt the 3 small nuts back on and get a puller behind the black boss it may work. Kind of explains why the Aluminium boss doesn't appear to connect to the centre bolt.

I wouldn't mind but changing the steering wheel is only due to changing the seats.
