I'd be very grateful of your advice on a little query I have:
I've got a 2000 E46 320d Touring with 185k miles on it now. I realised just recently that the inside shoulder of the nearside rear tyre has worn massively (rest of the tyre approx 5mm, shoulder down to cord). Clearly a typical E46 rear suspension bush problem.
So, I've got the rear up on axle stands now, bought a rear axle trailing arm bush removal/refitting tool, and about to start to replace those bushes.
Looking underneath at this stage whilst I was WD40ing, I wonder how far to go. The car's not worth a great deal (£1,000 I guess), but the engine is still great and returns good MPG. Bodywork is starting to rust in a few places. On the whole, I like and am happy with the car. My dad's had it from new, I took over ownership about 7 months/12k miles ago.
Am I best just to do the remedial work now, or do I want to start dropping the diff. and replacing the subframe bushes / possible new (lower) suspension whilst I'm at it? Anything else whilst I'm taking it apart? The front suspension bushes will be next on my agenda. I don't seem to have lots of noises or anything else suspicious from the rear, and the offside tyre is pretty much perfect. The tyres incidentally have done about 15k miles.
I've recently changed the MAF sensor (for a Bosch item), oil breather filter, cleaned the EGR valve, de-cat pipe to replace the broken cat, new K&N panel filter and an oil and filter change. This lot made a MASSIVE difference to the drivability of the car.
I've got another car, and basically a time budget of about 3 weeks. I could (hopefully) do the trailing arm bushes in a day or two, but whilst I'm this far, just wondered if it's worth doing everything else?
Any input gratefully received,
