Like other posts, my 300D has started some groans and creaks up front. I think I've narrowed it to the lower ball joints on the steering knuckle/lower control arm connection. I ordered the parts for it as the boots were almost completely gone... however as a temporary measure, I sprayed them down with WD40 and the sounds are gone for now. My question is this: How big of a job is it to break all of that down to drive out the lower ball joint and press in the new one? I have a puller tool and a ball joint seperator tool but before I venture into this, would like to get feedback on just how difficult a job is this for a shadetree mechanic like myself! Thank you for your reply.
