Hello I am just wondering if anybody can help I have had a knocking noise for while now and it has gotten progressively worse from reading posts on here I decided to change my ARB links but the noise continued. I decided to check all of the lower suspension components and I have noticed that the lower control arm rubber looks to be deteriorated so I have ordered a new bushing and mount however on closer inspection I noticed that next to the mount there is also what looks to be a bolt hole and I am wondering if this is whats causing the issue (the lack of bolts) and if it is not the route of the issue then whether it is a safety hazard not having one. I have included an image of the mount and the "bolt hole" below to give you an idea of what i mean. I will be changing the mount and bushings tomorrow and if anyone could give me an idea of how much of a pain getting the bush off and back on will be that would be great too. Thanks in advance.
