Well, today I decided to do my rear bearings on the e53 , if any one decides to try this at home, trust me its not easy
started off with the car on the ground and removed the main drive shaft nut , which came off pretty easily , wohoo I thought I could be on here, jacked car up and took calliper off and then removed disk , and here it went downhill
rear disks are knackered, so are the pads, but I've bought new pads, just needs to get new disks now. any whoo.
then you have to remove the driveshaft from the hub flange 2 hours later using a 5 lb sledgehammer it moved. then used a slide hammer to split the bearing (45 minutes).
then after another hour I finally got the old bearing off the hub, easy bit over
then tried to remove the old bearing off the car. following the autodoc video on YouTube started taking the suspension and stuff together, jacked lower arm up  then BANG
bloody jack moved  dropped everything to the floor, airbag fully extended thought oh FFS. I'm going to have to sort this out , ended up taking the entire inner hub off the car as I couldn't get to the 4 bolts. and then draining the air on the right side bag to deflate it so it wasn't  pushing everything down, removed the 4 bearing bolts, so now I got a x5 in bits awaiting parts
I'm hoping the airbag will just  push back up into itself I'm thinking reassembly is going to be a pain aswell
I took the speed sensor out of the hub it was filthy. should these be clean?
but to top it all , on way to parents, on motorway (70) car jolted threw up a trans failsafe error ,car felt like it was firing on 6  ,juddering ,tick over in D was 400rpm, I thought It was going to stall, no power on acceleration on take off, so needs codes reading on that one , that's ontop of the dsc inactive it threw up last week after the mass rain ( 3 yellow warning lights) (see above regarding speed sensor)
not touching it now till weekend, ill edit this with  reassembly

Sounds like your having a good day, The air bag will in my experience push back up into it's self. The sensor end should be reasonably clean, sides not really important, if it's come out of the hole in one piece it can't be that bad. I cleaned out the hole best I could with little round file and copper slipped the sides of new sensor, not had a problem since with it. As for the three lights, just had that, code readers showed front left wheel sensor faults, replaced sensor and still had lights intermittently, readers still blamed wheel sensor. Long story short it was the ABS module. Removed it and had it repaired locally £150. No more lights on. As for Trans Failsafe, nightmare, the above faults can play a roll in you getting G/B fault codes, yes, of course you need the codes read but do the simple things as well, check all the vacuum pipes, clean the maf and throttle body and their plugs

yeah the sensor, came out in one piece but it was very dirty. I'm hoping it isn't the abs module , I've just had another put on ,that failed big style. speedo dead car didn't  know it was moving , I'm just awaiting  all my parts to stick it all back together.
