I know some of you will have seen this before, but I thought I’d post it here before it gets lost when I pull the JA site.
This has to be one of the easiest jobs to go on a Jeep!
All you need is a 9/16 ring spanner, you might get away with a 14mm one, but it will be a very tight fit and some regular 10 mm washers.
The bolt has a nut welded to it so get your ring spanner on the nut and not the bolt head and just undo it! Place the necessary amount of washers behind the nut and replace the nut and bolt assembly and then check the tyres for catching on full-lock. You might have to add or remove the washers, but just use your best judgement. I think I use 3 washers on either side.
Here are some photos which shows the job.
