    It's cold out and if the front differential is low on grease, it will grind. Please check that first and hope for the best. Some shops never check this when the car is in for service. Also have them check the rear differential while you are at it.

You cannot pull the front differential and drive the vehicle. The wheel bearings are tied into the front axle, and won't properly lubricate if not installed.

2004 Buick Rainier four wheel is stuck in AWD drive all the time .


All wheel drive is just that-- All wheel drive-- not to be confused with 4 wheel drive . The difference is with AWD there is a 3rd diff in the transmission that allows the front and rear wheels to operate at different road speeds . When 4wd is selected that 3rd diff is locked and so both front and rear wheels drive at the same speed regardless of ups and downs in the road surface . This results in a torque wind up in the drive train and places load on "U" joints --splines --CV joints and gear teeth . The grinding on turning corners will be the CV joints trying not to flex because of the torque wind up . How to prevent this problem=== Do not use 4wd on hard road surfaces === as the tyres cannot slip to relieve the torque Restrict the 4wd use to snow , mud and loose surfaces TO fix the problem unselect 4wd drive and reverse several yards to release the pressure in the drive train and the actuator has a chance to pull the gear out of lock up. If that doesn't work check that the actuator is actually working

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.

Truck will only drive in 4wd, no power to rear wheels


I would guess your differential. Raise your rear end and try rotating wheel, it should make the other wheel spin the opposite direction. I'd the other wheel doesn't spin, I would say it's your differential.

04 trailblazer front wheels grind after using 4wd?


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.

I got a 96 chevy 4x4 and my front wheels aren't pulling. i replaced the acuator and still nothing. everything sounds like it is engaging but no turning of the front wheels. do 96 models have auto locking...


96 chevys have a ifs (independent front suspension) this give it more ground clearance but does not have lock out hubs, the cv axles go into the front differential an spin freely until you put it in 4wd, how this works is your transfercase spins the drive shaft that goes into the front differential an while you put it in 4wd it sends power to the actuator to lock the front differential. if your front end isnt pulling you either popped your 1 of your cv axles but if you did this you would know because it makes a very loud thunking noise while you're driving, my guess is you have a short thats not sending power to the actuator. check to see if the wiring harnesses are connected and check if the fuse that operates the 4wd in the cab of the truck is not blown. also actuators for these trucks are horrible they go out alot

sounds like your rear differential has some internals gone or going bad if it wont move at all in two wheel drive then its probably gone sorry. the planetary and spider gears need replacement or the splines on the rear axles are sheared off take you diff cover off( be ready for about half a gallon of gear oil to spill out.) look real good at the axle shafts and gears try to move stuff around. if there is excessive play that could be your problem. hope this helps

It doesn't take long to learn when and how to use your truck's 4WD system. Follow these steps and you'll feel confident about engaging the system the next time you need to get out of a slippery situation.

For a conventional system, where you can select 2WD or 4WD, the instructions refer to engaging 4WD. For trucks with permanent 4WD, they refer to locking the center differential.

Time Required:
varies
Here's How:
  1. Refer to your owner's manual to find out how to engage your truck's 4WD mechanism.
  2. When driving in snow, mud, or just going off road, shift into 4WD when you get ready to leave solid ground. If you have lockable front hubs, lock them for those operations.
  3. For severe conditions, use low range if available. Before shifting into low range you must either stop or slow down to at least 3 mph to prevent grinding gears.
  4. When you return to normal conditions, shift out of 4WD or unlock the center differential. If the shifter doesn't want to move from 4WD or the differential lock stays engaged, don't panic, becaue the problem is normal and is caused by pressure on the gears.
    • Try backing in a straight line about 10 feet and try to move the shifter again.
    • If the shifter still won't move, try backing in an "S" pattern while trying to move the shifter.
  5. If you have lockable hubs, don't forget to unlock them when you return to dry pavement.
Tips:
  1. Vehicles with permanent 4WD are set up for everyday driving, but not necessarily for maximum traction on slick surfaces. Engaging the differential lock increases the vehicle's traction capabilities.
  2. Do not operate a locked 4WD on dry, hard surfaces. Doing that could cause damage to the driveshafts, differentials or transfer case.
What You Need:
Owner's Manual

Good luck and remember to rate this solution.
