Hi there finally getting around to replacing rear swing arms on my 58plate 1.9tdi estate. They are in a very sorry state although still passd the MOT but swing arm bushes  do look as though they are just holding on and no more and arms look slightly twisted at the top bushing. Looks fairly straight forward but i cant budge the rear ofset adjusting bolts. Plan is to mark them on the old ones and then cut/grind them off and try to drive them back though the bush then replace with new bolts and new arms. If I replace them in the exact postion that they are in will that be ok or should I get alignment done plus is there any other adjustment on the rear suspension apart from the two top bolts? 

Thanks

Only if the tapping for the threads on the new arms starts at the same azimuth angle as that on the old ones. I give you roughly 1/360 that this will be the case.

Ah never thought of that. May have to try and remove bolts before cutting to check they hopefully match with the new ones.  Have sprayed bolts/nuts etc in a mixture of kerosene and oil for now. Will keep spraying for a few days and try again. May have to use the old blow torch as they are very rusty and seized solid. Tyres on rear are not bad but front are getting a bit worn and needing replaced  in the near future so will swap front to rear and monitor until I get the alignment checked.  Got to do the front track rod ends and probably anti roll bar bushes as well as bottom ball joints so an alignment check would be advisable considering the price of tyres these days.

They are eccentric bolts, if there is a datum marking on them, probably for the zero offset position then noting the angular position of them and fitting the new ones in the same place is a very sensible idea.

 

Where the thread starts is of no consequence.

Thanks, Had a look at the new ones and cant see any marks. Wll mark up old ones first and compare them if I can get them off.

Good plan, if you are lucky when you disc cut through you might be able to see the eccentricity and judge the angular alignment for the new bolts.
