2004 Silverado 4WD Lever is Hard to Engage 4WD

This is the last year for the manual 4WD selector on the hump. Been working fine till now. Got out in the sticks over the weekend and tried to engage 4WD Low range but the shifter was stuck in 2WD. With lots of attempts to make it engage, finally went in low range 4WD but still had trouble moving into other selections. I could hear some gears grinding in some of the attempts to change modes.

Now, before Thanksgiving 2016, a guy rear-ended me which only caused some light sheet metal and bumper damage. I was able to drive the truck for another month without any hiccups and turn it over to the repair shop for new bumper and paint. Never sensed any trouble with the drive-ability of the truck. Could the rear-ending have damaged the 4WD system? Auto Transmission, not manual shift, by the way.

I've never paid attention to see if the shift linkage is outside the tranny system so don't know if the selector is internal to the transmission or outside. Just wonder if it just needs some grease and adjustment? I'm gonna be pissed at myself for not checking the 4WD before I got the truck fixed for ALL damages and closed out the claim on the other guy's insurance, if the wreck damaged the 4WD.

Thanks for your ideas. LBJ

Its possible stuff could have shifted in the collision. You'll have to inspect the linkage. Have someone shift the lever through all positions. Look at the linkage while they are shifting. Look for binds/bends.

Another option is to unhook the linkage at the transfer case. Then see if you can move the shifter freely.

FYI, they had floor shift 4wd up until 2014.

Re: 2004 Silverado 4WD Lever is Hard to Engage 4WD

95S, Since I was in Fort Worth today, I stopped by the Chevy Dealer I bought it from. It was lunch time and mechanics were gone to eat for longer than I wanted to wait around. I'll get back to it one day soon, next time I'm in Fort Worth. Yes, maybe something got torqued a bit.

When I bought it in 2004, the Salesman told me it was the last year for the 2WD/4WD floor selector and also last year for rear disc brakes. He said that the 2005's had already gone to pushbutton 4WD selection. So, that's what I am going on.

Thanks for the tips.

I crawled under the truck this afternoon. Looked at the 2WD/4WD shift linkage - nothing bent or broken. No visible damage to the frame or anything that I could see. I did test it again earlier today and to try to shift into 4WD Hi Range, all I got was a grinding of gears when I pushed it forward. Never engaged the Hi Range 4WD due to grinding noise.

I've been able to get the floor selector lever into 4WD Low Range fairy easy. Still hard to move into 4WD High Range, but I can get in there by putting the transmission into Neutral and then pushing it pretty hard. Kind of grinds the gears, but it goes. Still not sure what's going on, but all I really ever need in the 4WD Low Range out in the boonies.
