easy job.

Jack up rear, as far as you can. Support with jackstands.

Remove rear seat bottom. push in the two red buttons and it will lift right out.
Unbolt rear seat back. two bolts, seat will lift straight up/

there may be plastic plugs covering the top bolts of the shocks, remove the nuts on top. Usually they are double nutted.

Remove the bolts on the underside.

Installation in reverse order.

Be sure to support the rear trailing arms (to which the shocks are bolted) before disconnecting the shocks.

Assuming you're talking about a W123 follow the advice written above but:-

When undoing the nuts on the top of the shocks make sure you stop the spindle from turning. If you have gas shocks installed and you inadvertently undo them you can injure yourself or the car!

So hold the spindle (about 7mm thick flat bit) and then undo the nut which could be a single nut with a plastic shake proof insert or two nuts used in a locked formation.

Under the car you'll have to undo two bolts that screw into the bottom of the trailing arm These can be rusted in place so soak with penetrating oil the night before.

The only reason you'll need to jack up the car is to get clearance to remove the shocks. If you are lucky enough to have a pit or a bridge you could skip this stage.

A find? Well it didn't turn out that way - I've probably done 80% of all jobs you can do on a W123 300D including an engine rebuild (well I'm half way through that at the moment). Hopefully in the New Year I'll actually be driving in my 30 year old new car.

If you've only got to do axle boots there is loads of information on this forum about it. Basically it comes down to lots of work and a proper job with thick axle boots or a quicker job that won't last as long with those flexible boots... I must confess I went down the route of grease and the quick cheapo boots as I have the type of axles that need to be cut apart to fit the real thick good boots... (This is not a popular choice with some)
