I dont know the term radius arms. If the trailing arm then yes if upper or lower arm then I dont think so.

The three-bolted mounting plate No. 5 on the lower Rimmer Drawing from macefee2 above for the front mounting, controls the toe in-out of the rear wheels. The bolts, 2 of one size, and another, are known to be very tight. It would be advisable to clean the area around the mounting and mark it so on replacement, you can get it as near as possible the same position. Use plus gas to assist in releasing the bolts.

Are the tyres showing any sign of uneven wear on either side of the tyre. This indicates the need for a 4 wheel alignment, even if you weren't taking the trailing arm off.

Hi yes you will need to get it tracked if you have had the radius arms off

as dave lincs says, yes

when you bolt 5 to the trailing arm you need to bolt it at the correct angle.

My mind is a bit hazy but this is what I seem to think. On 5 there is a line that runs horizontally below the single bolt hole for the trailing arm but I cannot recall what you have to line it up with, perhaps a line on the trailing arm. Get it badly at the wrong angle and you may rip the bush, a bit out and the bush will be under strain.

yes there is. horizontal line on the bush and on the arm casting... rave shows a rather ambiguous drawing but its obvious when you come to do the job.
