Shimming the rear diff mesh...
Ok so since it was built this is the first experiance I have had with removing anything for access and maintainence.
To remove the rear end its 4 screws on the chassis, and 4 screws on the chassis brace, simple!
this removed the back end
Next was remove the rear wing and diff case this was a further 6 screws, 4 for the diff case and two more also supporting the rear wing
this exposed the rear diff that pulls right out!
remove a further 2 screws that holds the driveshaft and bearings in and then just slide it out...
finally get your input gear off, place two correct 0.2mm shims between the bearing and input gear, put it all back together new threadlock, fresh grease on the gears and screw it all up
remember to measure the shims as its not advisable to guess which shim is 0.1mm and which is 0.2mm, measuring gauge is reccomended!
Job done! correctly meshed, and I had meshed it the wrong way so REMEMBER to keep the seperate shim sheet handy.
Maintainance and access was better than expected and not as awkward as first though.
