Question about 1998 GMC Safari

1 Answer

Will a 96 rear diff fit in a 98 awd

I just bought a 98 AWD safari and had the rear diff shatter. I also have a 96 - 2 wheel drive safari that I hit a deer with and was totaled. Can I put the 96 diff in the 98? I was told that the exchange books say it can but there are different gear ratio on the market. Does this matter? I am thinking that because I am going into an AWD, i need to be sure to have the same gears. But I do not know how to tell what is what.

Yes you do have to pull the axle and make sure you put everything back in the same place you removed it from. The ring and pinion shouldn't have to be bothered. You will have to remove the rear end cover to remove the axle. Its very easy to do. There is a pin inside the rear end that has to be removed to pull the axle. Pay attention to how you take it out and put it back the same way. It sounds as if you can do this with no problem.

What would make my 2006 Subaru forester, witch we all know is AWD, only have front wheel drive? I noticed it when the tires were spinning on the snow & ice. Only the front tires were spinning.


all wheel drive is not 4 wheel drive
there is a diff in the transmission that supplies power equally to the front and read wheels
when traction is lost on a drive set , the other set will remain stationary and the set without traction will spin as in your description
the same result will occur if you have both driver side wheels in a bog, the passenger wheels will be stationary and the drivers side wheels will spin
on some AWD vehicles and I thing yours has one there is a button that can be engaged that stops the transmission diff from acting like a diff and then the rear wheels will drive
read you owners hand book for driving in bad conditions

Just bought 2003 Aztec and the AWD is disabled how do i know if something is wrong . We could not find AWD button ? ??


AWD Disable indicator
The AWD Disable indicator is located in the instrument panel cluster. This lamp is used to inform the driver that the AWD system has been disabled and no torque will be applied to the rear wheels during a slip condition. The AWD Disable indicator is controlled by the powertrain control module via a class 2 message.
Powertrain Control Module
The powertrain control module monitors the data from the ABS controller and Rear Drive Module (RDM) for proper operating conditions. If inappropriate conditions are present the PCM commands the differential clutch pump actuator check valve closed, disabling the AWD system. The PCM also commands the AWD Disable indicator on.

If 4 wheel drive won't kick in do that mean awd won't work ?


AWD is 4 wheel drive with a diff in the transfer case to allow for uneven running between front and rear axles
If you have a 4wd drive button then that simply locks the centre diff so that there is no equalization of differences in the front and rear axles

Center differential


IF you are in constant 4wd then you will not have a centre diff unless you have an AWD. The difference is that AWD transfer cases have a centre diff that allows different road speeds between the front and rear diffs as in going over speed bumps and dips ion the road It is the same operation in the front and rear diffs that allow one wheel to go faster than the other when cornering. However in 4wd drive there is no diff action in the transfer case and both front and rear axles drive at the same speed regardless of speed bumps and dips in the road . This action produces what is known as torque wind up which results in the handling characteristics. This torque wind up places stress on all the drive line train and results in failures such as .that you describe.. This wind up is not noticeable when driving on loose surfaces slippery surfaces or in mud as it is allowed to escape when the wheels spin . If you have an AWD with diff lock capabilities then check that the diff lock is operating correctly

Durango AWD


The vehicle is always in AWD and that cannot be altered . There is a 3rd diff in the gear box that allows independent operation of the front and rear wheels to prevent drive line wind up . When you select 4WD you lock up that 3rd diff so that both front and rear axles have to turn. This results in drive line torque wind up so the vehicle must not be driven in this mode on hard surfaces as there is no means for the wheels to slip and relieve the torque wind up . To loose the wind up reverse for several yards and any actuators that are trying to move will be able to or drive on slippery surfaces to allow the wheels to slip

I posted about my AWD quit working on my 1990 Astro AWD.


What makes a car AWD is the fact that there is a diff in the transfer case in the gear box . This allows the front diff and the back diff to operate at different speeds from the road surface just as one wheel can go faster in turns than the other side.. To say that the AWD is not working would mean that it is not going any where as the rear or the front will have no drive because the diff will not be operating as a diff.

1990 Astro AWD. AWD quit working overnight while parked!


AWD vehicles have a centre diff in the transfer case and if there is no traction on the rear wheels then the front wheels will not turn. All wheel drive is not equal to 4 wd which you assume apparently. Check that there is not a diff lock button in the car to lock the centre diff turning it into 4wd vehicle in which case the front wheels would have moved the vehicle

Clunking and whinning when locked in awd


check the cv joints for wear. check rear drive shaft for worn slip joint splines and "u" joint wear. When you lock in awd there is no centre diff to allow the variations between the wheels and so you are experiencing a torque build up between the front and rear diffs . This put stress on the entire drive chain so any looseness or worn parts will display noises. Remember that the awd lock should be only used on surfaces that allow the tyres to slip and relieve the stress ( dirt road---snow---mud--ice )

1997 subaru imprezza 2.2 automatic AWD wagon, bought used, suspected last winter the AWD did not work. Just jacked up rear wheels with car transmission in park, and could spin either rear wheel with no...


there is a central diff(called a TORSEN diff)and yes it has splines on the output shaft.NOW this IS a front wheel drive car that goes into 4wd when traction to the front is compromised(slipping)they are not allowed to call it "quattro"or 4wd as its NOT.jack up the rear and block the front wheels,start the engine and put it into gear,the rear wheels should turn if the central diff is operating correctly.if not the best solution is to get a diagnostic done at a subaru dealer(you can then decide if you are capable of fixing it yourself or are willing for them to fix it)It is not as simple a system as some people would make out as you have electronics to control the front/rear traction.and the diagnostic computer they use is invaluable.AND EXPENSIVE.
