MOT fail sheet advice suspension arm bushes

[rudolf]

Hello All,
My 300d w124 Estate went for its MOT last week and the local guy here in Renfrewshire Scotland ripped it to bits unfortuneatly..some issues I think I can tackle such as Mcpherson strut rubber mounting , need advice on the following though..
Nearside /Offside front lower suspension arm bushes
Nearside/ offside rear trailing arm bushes bushes
Nearside /offside rear axle bushes MOT marked as DANGEROUS !!
Never had a go at suspension faults is it doable for competant DIYer?
Anyone able to estimate the cost of the above to see if its viable ?
So far have changed power steering pump , door motors , fuel tank leaking hoses and gave it a paint job, and fitted green tech veggie heater kit mileage is about 187,000
Would like to keep it going as I have recently also changed injectors and had the brakes exhaust done
Thanks for any advice
Regards ,Rudolf

You can buy most of the rear suspension arms complete with bushes. Reasonably easy to replace if you have a good socket set- tools. You need to know exactly which of the 5 arms per side have been "condemned" to price up the job. You can buy genuine MB parts using your chassis number which means you will get the correct part. If you go after market I would suggest Lemforder [OEM to merc] think ECP or GSF stock them.

If it needs those parts then it is likely it will also need front ARB bushes, engine mounts & front prop doughnut

all easy to replace, be sure to check the nibs on the front bushes are correctly placed, i have seen instances of arm supplied with them in wrong. they should be at the horizontal position, do a search on hear to find out more.

you will also need the front aligning afterwards to set camber ect.

Would a worn front propshaft doughnut exhibit any characteristic symptoms of impending failure Nick - vibration/knocking/ clonks on take off etc or are they generally "silent" before impending failure ??

That is not correct for 124.

for the front wishbones the manual shows the following:-

front bushes - flats should be horizontal

rear bushes - flats should be vertical
