Transfer box signs of trouble

(1/3) > >>

gords:
Do transfer boxes have specific potential problems, like the gearbox that starts crunching into 2nd gear, or do they tend to just carry on working?

The above question specifically relates to 300 series manuals :wink:

Sounds like wearing syncromesh in the main box to me. Could be a sign of an overdue oil change. I think LR changed the recommended oil for the later R380 to MTF-94 rather than ATF that was put in the LT77.

HTH

I know that happens to the gearbox, but I was wondering if there were "typical" things that happen to the transfer box.

Only problem I know of is the spline wear problem, but on the later boxes LR fitted a cross drilled gear wheel to help with the lubrication problem that caused the wear.

HTH :)

Can you "tell" that a transfer box has spline wear by external inspection or driving?
