One of the first MOT problems was poor braking efficiency at the rear, I could not sort this one out. However a mention on the difflock site had Zukijimny mentioning bias valve.
The Jimny has a variable (automatically adjusts with load) bias valve location above the rear axle.
It is mounted to the body and attached by a spring to the axle.
Of course, for the MOT the car was emptied, including removing the spare wheel from the back door (because of concerns about obscuring the rear lights) meaning there was no weight (no seats, no tools, no carpets - nothing). With no weight in the back the bias valve is basically switching the rear brakes almost totally off. There is an adjustment on the valve but mine was almost fully adjusted already due to the spring lift. Therefore I loaded up the back with the spare wheel and tools - and passed!

So following on from the KingPin bearings I have moved onto the wheel bearings. Again I have prepared a "How to" guide with the full details of the change so there is only an overview here!
The problem with the front wheel bearings is that they are hidden behind a special lock nut.....
I met up with Baz today at the Berkshire 4x4 show. As you can see below he has a smart looking Jimny under construction. Currenty it is running 31" Insa Turbo Sahara tyres based on a couple of inches lift. He has cut away the bumper to improve its clearance and underneath the back is a nice sounding Cherry Bomb Exhaust.
So if you have been following this website you will know my car failed the MOT and one of the factors were the Kingpin Bearings on both sides.
It was a fair decision and I have now changed them.
A number of people have offered advice on which bearings to use as some bearings do not seem to fit. I used bearings from BigJimny Shop which fitted ok.
As you can see the hubs were full of water, oil and grease....
