Anyone notice a thump when they engage the trans. case into 4hi while moving? I just started noticing it.
Thats what I figured. I just noticed the noise yesterday. Once at 65mph, and once at 35mph. I wasn't really sweating it, just wanted to make sure it wasn't a known issue. Thanks Bob.Mine thumps lightly ( sometimes ) - it's as the gears engage. Other times no noise.
your first post says 4hiAnyone notice a thump when they engage the trans. case into 4hi while moving? I just started noticing it.
and then what? so did you shift into 4hi at 65 then? i don't really know shit about 4wd trucks that's why i ask.4lo yes. 4hi no. That's why they call it shift on the fly. Good call though.
Yeah, I got it ass backwards. Sorry.your first post says 4hi
You have to have the truck in Neutral with the parking brake engaged to shift into 4lo.so what the fastest recomended for 4LO. I try to keep it under 10.
Good idea. I'll give it a try. Thanks.Try backing of the gas a bit when you push the button, till it locks in 4hi. Seems to make an easier time for both front and rear drivetrains to match speed. If I don't back off I get a clunk. But lifting of the pedal for a second allows me to engage smooth as silk everytime.
