04 trailblazer front wheels grind after using 4wd?

Front wheels grind after using 4wd, front left wheel wants to lock up when 4wd is engaged. When switched back to 2wd frnt wheel seems to have some resistance on it and there is grinding noise, I can;t tell if it is from both wheels or just one.

You probably have a front drive splined disconnect assembly that has gone bad. This assembly engages the front differential when 4WD is selected. Below is a figure of the item, it is on the passenger side of the differential area.

    Thank you very much Freddy! I just went out and lifted the front end up took both tires off, right wheel spins without much resistance and no noise. But the driver side has alot of resistance and anoise coming fromthe point where the inner cv jointattaches to the differential. Would this be from what you suggested or is it the cv jointor something else? Thank You

    I was thinking it might be the CV joint/axle, or is there a bearing to go bad in at the point where the axle and differential meet?

    Yes, there is an inner bearing as well as the differential gears. Sounds like a disassembly will be needed.

SOURCE: noise when in 4 x 4

Bad news... It sounds like you have a broken/stripped axle. I would start at the wheel and start disassembling from the outside in. It may just be a stripped spline in the spindle.

That Sounds a lot like you have a Gear Broken off inside the Transfer Case. Not a Cheap fix or Easy Either But, Necessary

It does not seem that sufficient diagnosis was done. No, you cant give a specific diagnosis like that without tearing unit down. It's likely that they told you the most common failure and left it at that. Likely there is a problem with your unit...I think this becomes more of a trust issue than a mechanical one. A second opinion from an independent reputable shop may help but either way, you need to have it fixed. In not using it much, it makes me wonder how it got worn.
good luck

Front differential?

Sounds like the transfer case is not engaging into 4wd. It has a solenoid or actuator, but it could be damaged inside too.

2005 Trailblazer XT won\'t go into 4WD. Front hubs don\'t engage with switch in cab. It will gear down to 4wd Lo but front wheels won\'t engage. Please help. Can\'t afford the dealer!

i've been told it was the 4wd actuator located on the passenger side near were the cv joint goes in to the front axle a good test is to floor jack it up so both wheels are off the ground and have someone on the other side , put in nutrual turn both wheels one way at same time and the 4wd drive shaft should turn if not its your actuator, costs about $86 for anew actuator and takes about 5 mins to change once you have the tire off

04 Trailblazer LS won't go into 4WD. Front hubs don't engage with switch in cab. It will gear down to 4wd Lo but front wheels won't engage. Please help. Can't afford the dealer!

What do the lights on the 4x4 selector switch do when you switch to A4WD or $HI or 4LO positions? Do they blink and revert to previous selection? Has the Transfer Case fluid been changed at 50K intervals?
There are actuators on the Transfer Case and Front Differential that control the application of power to the front wheels. These actuators are controlled by the TCCM (Transfer Case Control Module). It takes a qualified 4 wheel drive technician to diagnose these systems.

2003 f150 crew 4wd Lost 4WD tranfer case locks

Lift and support the front of the truck so the front wheels are off the ground.
Key on, engage 4x4 and try to turn the front drive shaft.
If it turns it is a problem with the transfer case.
If it doesn't it is a front axle engagement problem.

Chevy Tahoe 2001

Place vehicle in 4wd (high or low). This will hold the front drive shaft still for the rest of the test. Jack up the front end of the vehicle. Remove the actuator. Have a buddy spin the right front wheel while you use a long punch or screwdriver to try to manually engage the diff. The left front wheel should spin in the other direction if the diff is good. Also before you check the diff you need to grab the front driveshaft and make sure it is locked, If it spins freely when the truck is in park and in 4wd with the front end raised then problem is in transfer case. If you can't make the diff engage manually with punch then the problem is in the diff. If front diff engages manually then the problem is the actuator. Hope this helps..
