The rear disc brake conversion is a pretty much a bolt on mod. The calipers are MK3 Golf, not sure on
the discs though? Guess something jeepy anyone know?
Exhaust is done, the TJ sounds as quiet as a mouse (Boo!)
The culprit of the quietness:
Front axle pinion bearings were shot and the oil seal had also failed. So fresh bearings and oil seal
were called for
Diff cover off, remove the retaining journals. Mark up the journals and assemble exactly as you removed.
Out it comes, no spreader plate special tool needed.
Remove pinion retaining nut. This is generally a stubborn bugger.
Pinion out, here's the crush spacer that sets your bearing pre-load. Nissan Axles use these crush
spacers too. However a mod they do is to set the pre-load, then remove the crush spacer. Measure the
length of the spacer and replace it with a bush to the same length.
Remove oil seal flange:
Drift the old bearing shells out of the diff housing. KEEP THE SHIMS AND REFIT, WITH NEW SHELLS (in
bering shell)
Fit new shells
Pull off old inner race from pinion and refit new. I used the old crush space and some 1" 3/4 pipe to
press into place.
New bearing on pinion and a fresh crush spacer;
Place the outer bearing race into the nousing and then re-fit the oil thrower. Then onto a fresh oil
seal:
Pinion shaft in and ready for tightening. The bearing needs a rotation preload of 3-5Nm, this basically
means that the nut needs to be done up to somewhere between 240-260Nm! Bloody tight....
VIDEO OF ROLLIN TORQUE
Replace bearing journals and torque them up
Front Axle done.
Rear axle ready to chuck under:
A little extra fab to appease JJ
Axle under and brake lines etc fitted.
Asylum fitted these funky things? They give around a 2" lift but are adjustable for more.
Onto setting up the axle alignment and seeing how it all works.....
Front axle will get radius arm links sometime in the future. So at present its like a Half long arm
mutant jeep..
