    coupe rear uneven

    have a 1.8 02 plate coupe

    had it lowered 40mm and noticed it was lower on drivers side - so took off rear springs and put standards back on and its exactly the same problem - its uneven

    any ideas? shocks?

    When it was lowered, were both sides done at the same time, so the axle was hanging under its own weight at any time?

    Where the springs fit on the under body there should be some rubber thingys that the springs fit on to, are they both there on each side?

    Yep it sure does, if the shocks were removed as well.

    It's not designed to hang under it's own weight, and you should always do one side at a time and leave one shock on to take the weight of the axle.

    If the above is what happened, I'll tell you how to fix it, rather than type loads of irrelevant stuff just now

    a bit of science first...

    The back axel is only held on by two bolts that pass through the main bushes (one each side) - so letting it hang under it's own weight can cause the bush to move slightly in relation to the mounting bracket on the body, or even strain the bush. So when you refit it all the axel is is a slightly different position in relation to the body - it sounds daft but it can make a difference.

    So what you need to do is...

    Jack the car up (one side at a time) and support it on axel stands, and then get remove the spring, shock and rubber seats.

    Now get a trolley jack under the trailing arm, and jack it up until the the distance between the two spring seats is 168mm (cutting a bit of wood or similar to the right length helps no end with this bit).

    When you've got the right distance, undo and then retighten the main axle mounting bolt to 90nm (66lbf ft) and then tighten another 60 degrees and then finally tighten another 15 degrees.

    Then do the other side

    That should sort it, but only ever meausre the ride heights on perfectly level ground

    when you say "to 90nm (66lbf ft) and then tighten another 60 degrees " does that mean i need a torques wrench *sp*

    i kinda understand what you mean, am sure my bro n mates will as they will be doing it, i will just pass tools

    is it bad to leave it how it is? or does it need sorting ASAP?

    thanks for you help bud

    Yep you need a torque wrench to get them to the right tightness.

    It's not a big job TBH, plus you can swap the suspension over whilst youre at it.

    It's not too bad leaving it like it is, as long as it's not too far out, but like most things the quicker it's sorted the better.

    PM me your email addy and I'll send you some more gen on the job - it'll be tomorrow evening tho before I can
