detroit locker installation

Range Rover Blues:
If you can lock the pinion with some grips it helps.  Finger tighten the diff carrier bearings (crownwheel part) until there is now discerneneble backlash at all, finger tight both ends.  Wind in preload on the bearings (pushing the crownwheel away from the pinion) untill there is 0.10mm backlash at the outside of the crownwheel.  You can measure this with a feeler gauge but it's far less acurate, you may need to cut the feeler into strips.  If you get it too loose it will rumble, not loud but annoying.  Don't set the preload too high and don't forget to lock the bearing caps when you are done.

chuggaman:
thanks for all your help guys

got it all together ok

i have the tiniest bit of backlash.tested by holding the crownwheel still against the casing.then moving the pinion flange.

driven it a short distance and all seems ok.

lets hope it stays that way

thanks again

We give these components a lot of hammer off road, so I would suggest setting it up 'by the book' using engineers blue.

In fact, despite doing pretty much most stuff on the racer myself, this is one of the areas that I have outsourced ( :shock: ) at the moment.  Partly because I have someone that I trust who does it for a reasonable price, but mainly because I want to be as sure as I can that this vital component is not going to fail in competition.

Hope your's works reliably, I am sure it'll be fine...
