Death trap

[E30m42cab]

I know this post is for the wrong car (my (92 E34 525i) but I could use some ideas from Graham, Joseph, and Dan etc... So my piece of crap E34 is giving me a headache. The drivers side rear wheel is f-ed up. I jacked the car up and I can wiggle my wheel back and forth. It grinds when I drive it, almost like the half shaft is binding, and I can actually move the half-shaft in and out (back and forth between the diff and the hub. I never had any hum that I would accociate with a worn bearing though, but I'm assuming that is where I am getting the play from, but why would my half-shaft slide back and forth?

Sounds like the bearing is the culprit if you have play in the wheel. The halfshaft slides into the bearing. Check the CV's too. Bearings are a bitch to change - I wish you luck!

You need a pretty big socket and one hell of a rattle gun to get the lock nut off, and then getting the bearing out is pretty fun. Last time I just ended up dropping the subframe and doing it on the ground. Its actually alot faster in the end as there is no room to swing a hammer otherwise.

or you could use bearing pullers lol.

I too would suspect the bearing, never done one but I have been told they are no fun!

The half shaft will move in and out of the output and input splines a little when new, there is nothing wrong there, though if its excessive (including excessive up and down play with the end float) you may be up for a half shaft (whole new one, not sure if you can buy just the separate splines and cv cup) if the splines are ****ed, also, the bearing will need to be replaced.

You could always just swap the m50 from the e34 into the e30 cab, and do away with unnessesary e34 yukkyness?

My 2 cents anyway, hope those splines arn't rooted. Just another "con" about IRS is those bloody half shafts!
