My truck just failed wof on lower inner suspension bushes. I bought the bushes today and am planning to replace these myself to save a few bucks. Is this a big job? Is it difficult to remove the control arm and does cv joint get in way. If stuck I will get someone to press out the bushes but looking some advice on removing the control arm if possible. Thanks in advance

We just reamed out the old ones with a cordless drill and used two big washers and a large g clamp and dish washing liquid to press the new ones in on the father in laws rano.

From memory we just jacked it up and undid what we needed to. Did it with arms still connect at hub end
