M235i : Replacing hub assembly bearing

https://www.newtis.info/tisv2/a/en/f...uckle/KHOmg9S8

Man, why does everything always look so easy on paper but so difficult in real life?

The center bolt in the center of the hub is easy to remove following the steps. You need someone to step on the brakes while you use a breaker bar to unscrew it.

But .... but ... but ... the 4 bolts that holds the hub assembly to the drive axle is truly a pain to remove --- the axle is in the way.

TiS instructions are not realistic. I think we need to remove the rest of the suspension pieces to have enough room to work out those damn 4 bolts.

I got one unscrewed but it cannot come out because it's blocked.

Any suggestions and help would be great.

The TiS instructions are correct.

You just need to use the correct Torx bit. The original requires a T55 Internal Bit to remove the 4 bolts that retains the Hub Assembly + Bearing. If you use a Hex bit, you will get into trouble. Just do not do it.
It takes a bit of maneuvering with shorter and longer torx bits along the away because the bolt protrudes more and more as you back it out and there are suspension arms, axle bellow and strut in the way.

Note : the newer updated new bolts needs a T60 torx bit instead.
There is no need to remove any other pieces of suspension arms or the strut to get the Hub Assembly off.
