The standard Jimny rubber mounts are notoriously weak when the Jimny is used in anger offroad. It is common to break one, you find your transfer box lever suddenly leans to one side or the stick seems to disappear into the floor and everything shakes and rattles.
In the early days of modifying Jimny's, everyone developed Polybush style heavy duty mounts. Indeed I have a set of mounts which were early production models from Off-road armoury. However, the material used in Polybush items or variants is hard and unforgiving. Yes, it is long lasting and tough but it does not lend itself to comfort. That is why I got rid of my caster correction bushes in the radius arms and went back to rubber based ones, to improve the ride.
The same can be said of the transfer box. The heavy duty polybush style mounts on mine have lasted well but they transmit every vibration and bump onto the chassis and body work.
BigJimny has dual batteries fitted. A slightly enhanced standard battery for starting and a large battery in the boot for the winch. Having just replaced the batteries when rebuilding BigJimny, I decided to put a monitor in. A quick google showed a number of expensive systems but also a new cheap system from the Chinese discount sites.
So with the MOT passed, we have been driving around this week. Unfortunately, there is a vibration or "push" in the drivechain. I took the rear propshaft off and found the UJs were notchy and very stiff. Taking them apart showed not only rusted out UJs but also a bent yoke. So a new yoke is on order and the car is back in bits in the garage. However this time is it only short lived and I took the opportunity to get on with the interior.
