Just had the transfer rebuilt with new OEM ring and pinion, shafts, bearings and seals. Running redline shockproof heavy. How long will it take to run it in before I can drive it hard? I have put 250km (155 miles) on it driving gently so far.

Also when should I be changing the fluid out?

 

Ok so if anyone else was wondering, 100 miles for an OEM unit is the recommendation.

 

interesting. I think mine got about 5 miles of break in, maybe...

 

I don't think u have to be too worried about break on with a tcase man

 

155 miles I'd say ur ready to rip
