Any other tips??
thanks.
Joe,
where in Kansas are ya?
I live in liberty, mo and it was cold there, coooooler than here in MI.
When was your truck built? pls check the build date, mine sat at stealership for a year before I bought it.
I think the only breakin warning in the owner manual is about towing during the first 1000 miles (or could be 500).
Oil - dump factory fill and get a syn oil change. Trust me, you want your oil to flow during cold start.
rear diff - drain and fill after x miles, you pick the miles. I used mobil gear oil,
front diff - same
transfer case - leave it alone
tranny - go to big rig/truck place and buy a case of transynd and spin on filter. after 5 k miles spin off the trans filter and replace it, and replace a dixie cup of transynd
FYI:
my truck came with the front differential gear misaligned from factory, and I am pretty sure same is going on with the transfer case. so take your truck our on the hwy BEFORE you buy it and turn off all music etc and listen to it under LOAD in 2wd and 4wd HI. listen for howl/roaring under load.
good luck
