Hi all,

 

Having a small issue with my front wheels binding on full lock in 4 wheel drive mode. It doesnt do it in 2 wheel mode.

 

I thought maybe the fluids but I've changed them and still it happens. 

 

The wheels are fine in a straight line in 4 wheel mode.

 

Any ideas?

Thanks

On hard surfaces they will bind, unless it's the awd version.

 

The outside wheel has to travel farther in a turn than the inside wheel. If it's fully locked it can't do that without something slipping. Be it the tires slipping on the ground or something slipping in your transfer case.

Ive had the truck since new (4 years) and it's never done this before. Its not an AWD.

 

What would be the point of a 4x4 mode that can only be used in a straight line or gentle bends? Sorry I might be dumb as it doesn't make sense to me.

 

 Thanks.

If you've owned it 4 years then by now you should know it is a normal function of a 4x4 vehicle when tires are driven on surfaces with almost normal grip levels. All 4wd vehicles have binding when you are near the full lock point when turning. My 2001 Silverado did this, my 2010 Sierra All Terrain did it, my 2014 Sierra All Terrain did it as does my 2016 Sierra All Terrain.

 

You wont notice it on grass, mud, offroad or snow/ice as the front wheel are slipping enough to not be noticed. Get the front tires on pavement that is only wet and you will notice it if you are fully locked in 4wd Hi. If you are in Auto you may not notice it as once the system doesnt see tire slippage and the decay period has expired the system releases the transfer case clutches to go back into 2wd mode.

Is this a joke?! Funny story though... and youll immediately get where this is going. 

 

I cant remember why, and it doesnt matter, but my wife was driving my 1999 K1500 with push button 4x4. It was a nice dry summer day. She calls me in a panic, saying shes stuck in a parking lot. The truck wont turn at all! I talk her through some possible issues.... The first thing i asked was "is it in 4 wheel drive?" She immediately responds "No!" Do you hear any grinding or clanking? No. Okay, so I drive to meet her,  get in the truck... drove it 20 feet and look down to see a little orange light lit up right next to the label "4 HI"! 

 

Of course she didnt do it. She was the only person to drive the truck, but she didnt do it.  :rolleyes:  Im sure she hit it inadvertently , as the button is right behind the gear shifter.

      Blazer is all put back together. Another hard-won battle. The 4.3 is not easy to work on in such an archaic and narrow chassis originally designed for an inline 4.   My baffle issue is solved. I returned to the OG junkyard but was ready for a fight. The Blazer I had picked from was stacked on another vehicle so I had no idea how the heck I was going to get myself to working height to pull the front end apart. I had seen an S10 pickup on the ground so I was hoping the part would be the same, AND, I couldn't remember if the S10 still had a front end or not. But I didn't need to worry because it turned out to be my lucky day. The yard had just taken in a '98 Blazer, sitting right up front, on the ground, with room to work around it, and the front end hadn't been hit. The baffle and all the clips were factory perfect. I also scored another good handful of odds/ends and the whole shebang only cost me $20.   Got everything back together and it fired right off, sounds good, runs good. I've got a little coolant drip from a lower water pump bolt (D'OH!!). I did the right thing and snugged it down a little bit, and of course that didn't fix it. Yet again, I will have to soak everything in coolant to drain it down to the water pump, remove the bolt, and attempt to re-seal it. Nothing is easy on this truck. Nothing. But now all the radiator plastics are correct, snug, and fully functional. No more rubbing on the cooling fan. It runs, drives (took it for a 30 mile drive last night), no Check Engine lights, EGR is working, no vacuum leaks. We're getting closer...   The replacement wiper motor arrived yesterday. The tailgate was already disassembled and waiting, so I threw that in. It works! Sort of. Two new issues on the list. While the motor is strong enough and the gears aren't stripped, the wiper is hanging up on the bottom of the rear glass. This is the old style where the lower half folds down like a truck tailgate, and the glass swings up, and they meet in the middle when closed. The glass isn't sitting flush with the tailgate, now that I look at it. No rubber bumpers that I can see for adjusting, so I'll have to look at the hinge adjustment to see if I can correct it. Also, the washer/squirter just dumps fluid underneath the truck. The lines actually run inside on the floor so I'm guessing the tailgate is soaked at the rear trim and the line is disconnected. There's also a drain there....probably for this reason.   The leaky water pump bolt was really disappointing. JUST STOP LEAKING...OMG!!   Replacing the window motor and a rear door speaker are still to do, and then everything will work. I want this to feel like a "good" vehicle worthy of dropping $600 for new tires before I do. That means no leaking first. I hurt, and I'm kind of cranky, so I'll probably take a day of rest and do the water pump again tomorrow.

      Just saw on Jay Leno the new Scout. That’s the way it should be done.

      EV's have their nuances too. Best to operate the current type of lithium batteries between 20-80% charge. No real need to charge until you hit around 20%. Occasionally charge to 100% when needed. Longer term storage, battery should be 50-60%. At least those are the guidelines for our iX. We've been exceptionally good to the battery in that car...easy to do when you can charge at home like we can.   EV's lack so many of the rituals and so much of the visceral feeling ICE vehicles provide, which is why I think they're hard to accept for a lot of gearheads. They're fun in different ways, though.

      We have got a lot of rain lately, we needed it. Storms/lightning took out a floor fan. Dirt roads badly rutted from run off.   Power here is sketchy, whole house surge protector in the service panel and all electronics plugged into surge protectors. My biggest concern is my stereo, I've been an audio nut for years. $25 k in equipment. Stereo is on it's own special surge protector.
