any ideas?

i dont know if some of you remeber

--------------------------------------------------------------------------------

but i sank my 06 awhile back---


well ive replaced starter, alt., batteries,and a complete detail but i still have a problem....

well 2 actually....

1. the truck backfires or pops if you will under a load(anything over 2200 rpms) any ideas? (maybe mass airflow?)

2. front end is locked up front diff will not disengage--in other words if i engage 4wd the truck will not move--i put back in 2wd its ok-i disconnected the front driveshaft and trans. case is ok...any ideas?

1:??

2: did you pull the front diff pan after sinking it? could be full of water, or had enough water to gauld things up inside. does it clunk when you engage 4wd?

the back firing may be water in the fuel system.

i pulled the front diff. and it was full of water so i cleaned it and put everything back together and still doing same thing(do they have clutches like rear?).....no clunking just locks up as soon as transfer case engages...when i took the drive shaft loose i could not turn at all.


im going to replace mass airflow and see if that helps(per #1)


thank guys

I'm pretty sure it's an open Differential, so there shouldnt be any clutch's or LSD in the front, possibly the bearing is frozen, or some kind of damage to the u joint? is it electric or manual hubs?

there electric with the overide on the hub (it has been checked also-hubs)

i know its a bad idea but i thought about driving 2-3 mph and engaging to see if frees up--when i got stuck and left truck front end was working fine..there was alot of metal shavings when i pulled the cover--ahh about normal i guess for 40,000 miles-it just feel like something is bound up

ty good
