    The front suspension is basically renewed and it feels infinitely better for it. Having said that, the side slippage of the rear axle, having been 4-wheel trackes was 14m/ km. The limit is 20m/ km and the front slippage was just 1m/ km.

    Would replacing these bushes be within the realms of DIY?

    As a sub-question, if the rear springs were cracked (common E36 problem) would the NCT turn it up? My last E36 passed through 2 garages before someone cottoned onto the fact that one of the springs was cracked.

    RTAB go on all of them. They aren't too bad too replace if in your in anyway handy with your hands.
    1. Jack up the car, support on axle stands.
    2. Take off wheel
    3. Drop down bracket that holds trailing arm to chassis (3 17mm bolts from memory)
    4. Remove bracket from trailing arm. (1 bolt through the centre)
    5. Now to take old bush from trailing arm, metal inner and rubber should fall out. The outer metal sleeve is soft metal, so it can be cut with a hack saw. Some people drill the sleeve or use an air chisel.
    6. Now push in the new bushing, for this i would use some M8 or M10 threaded bar and spacers, to push the outer race of the new bush into the trailing arm. Some people use a big G clamp for this.

    I've done these a few times. Take good care as your working fairly close to the petrol tank.

    Bushes tend not to be the problem at the rear of an E36, its usually the balljoints top & bottom of the hub. They are fairly straightforward to change but do need proper alignment people/equipment to sort it.

    I use Dave McCann in Blanch.

    Cheers

    Dunno who you were talking to but cracked springs are not a common E36 problem. Replace them as soon as possible. Part could come out and shred your tyres.

    Rear trailing arm bushings are a problem in them. But they cause the tracking to move when you plant the shoe. Would have nothing to do with the car not tracking.

    OT: If you plan to change the bushes your self you will have to break out the old ones.

    Or if you go powerflex bushings to replace the original RTAB it's as easy as just sliding them into place. But make sure you use the lube supplied.
