Fitting guide for Astra H rear beam bushes

 

 
 
 
Here is the method of replacing the rear bushes that we have found most easy . The whole job should take no more than 3 hours to complete requiring only a range of torques bits , set of spanners , allen keys , a selection of chisels and a decent hammer . 
 
Crack the rear wheel bolts off
 
Firstly jack up the rear end of the car and make sure you are happy with the way it is sat  , be sure to use axle stands or a decent set of blocks as we cannot suggest you work soley from the jack . 
 
Remove the rear wheels . 
 
Support the rear beam with the jack and apply a little pressure , undo the bottom damper bolts .  Release a little pressure from the jack and allow the rear beam to drop a little , now remove both rear springs . Re apply some pressure to the jack to align the damper bolt holes  , wind the bolts back in and tighten them back up    . 
 
Its  worthwhile  taking some time to mark up the brackets that the rear beam bushes are held in ,  a decent marker pen will be fine for this - purely to aid you refitting it back on and getting the alignment somewhere close as a starting point . 
 
Now slacken the two pinch bolts that go through the rear beam bush , one each side .Completely remove the nut if you like . 
Slacken  the bracket bolts each side and continue to wind them out making sure nothing untoward is going to happen , when all six bolts are removed the rear beam should hang there safely off the dampers 
 
 
You may want to use a decent block of wood to allow the front end of the beam to hang down nicely , this allows you to continue working with ease .  
 
Its now time to remove the rear beam bushes , this is easy , be patient - they will come out . 
 
Looking at the bush , there will be a rubber/plastic cap on one side , this is the side you need to be on . 
Once you have removed that it should look as below 
 
 
Now  Pick up your favourite chisel and hammer , and position the chisel on an angle such as below . 
 
The idea is to collapse the outer aluminium housing allowing the bush to come free , work around the bush collapsing it in . You may also want to do the other side as well . Be careful to avoid damage to the bore in the rear beam as this is where your new bushes will fit . With a little patience the bush will come out , its recommended  to put the kettle on after the first one is out !! 
 
With both bushes out , take the RND rear bush and insert it from the inside of the car . The bush will only fit one way so you can't go wrong on this .  It should look as below .
 
Now take one of the pinch plates and bolt this onto the other side of the bush , take care that the plates are sat square and that the bolts are winding in properly .  Repeat this process for the other side using a small amount of copper slip or a suitable lubricant on all the bolts and mating surfaces .
 
 
Both sides should now look the same , make sure all the M8 cap head bolts are nice and tight . 
Take the axles and slide a seal over it , the thin portion of the seal should be facing the bearing and the small step on the axle should go into the bearing , it will not fit together any other way so again you can not go wrong . 
 
Now take the bush brackets and slide them over the bushes as they were before ,  re insert the long pinch bolt as before also
 
Now continue to re assemble the rear beam as it all was before . Using the marks on the brackets that you made , align the rear beam up best you can before tightening the three bracket bolts on each side .  
 
 
Ensure you also refit your rear springs !! 
 
Its strongly recommended that you fully check all your rear end alignment as its easy to be a little out - the better this is set up , the better your car will feel
