Hello, about 5k miles ago I changed the front wheel bearing on my 1988 360. Now I get a sort of groaning sound from them which becomes more obvious when steering to the left and to the right. Close to the legal, the groan becomes a bit of a roar! It seems to come from the offside front wheel. I tried to retighten the bearing as per Haynes manual - I did exactly what it said about tightening to the specified torque, backing off so much and peening over the nut. I also checked the tracking. Still it groans.
Does this mean new bearings again after so short a mileage?!?!?! Or, should I do something else to re-tighten them?? Or could it be something different??
Any clues, very much appreciated. Cheers, bogbasic.

Jack the front end up and spin the front wheel. Feel for notches and listen for a humming noise. If you have either its probably the bearings.
If they need replacing again I strongly suggest that you go to the dealer for them are the after market ones tend to be low quality.
If buyiong atfter marker use SKF or FAG only

Sounds very much like a failed bearing again - can't think of anything else that would be so obviously steering sensitive.
If it is the bearing them a new one will be req'd - if it's at the point of noise them retightening will make no difference (assuming correctly fitted in the first place) and overtightening will finish the job off and induce rapid failure. You can't re-use a noisy hub bearing.
Off the top of my head - causes could be any of the following.
Faulty replacement bearing set.
Incorrect fitting of set.
Incorrect torque,
Slackening of hub nut allowing brg. to run loose, (re-useing old nut will cause this),
Insufficient greasing of new races,
Too much grease (yes too much will kill a bearing),
Contamination whilst fitting,
Not changing outer tracks,
Damage to outer race/s whilst fitting.
In sevice damage - impact with kerb.
There are probably a few others but that's the obvious possibilities.
If you're confident you fitted them correctly I would think the most likely cause is either a poor quality bearing set, or inadvertent damage to one of the outer tracks when pressing them into the hub. (it can easily happen even with the factory mandrels - the tracks should be pressed in - not walloped in with a hammer).
You need to jack the wheel up and spin it while listening and feeling for roughness - but the change of noise under steering is pretty damning.
