Wanting to replace both the wishbones.
The famous bolt problem as cannot remove the one bolt because of rusted bolt in the bush.
Seen its advised to use a hacksaw blade to cut the bolt for removing the arm. Is there any reason why a angle grinder cannot be used instead being alot easier.?? RRS HSE SDV6 2012

I would think your main obstacle in using a angle grinder would be restricted access to get in there to cut the bolt without damaging the arm/bolt mounting brackets on the chassis. If you could borrow one I would have though a reciprocal hacksaw unless you have one would be your best option.
