Question about Chevrolet S 10

1 Answer

I just traded for a 1994 ZR2 4x4 6cyl and when I engage the 4x4 the rear wheels go into the lower gears but the front wheels do not engage. The guy said he put in a new push button and a new vacuum hose. What should I check to fix?

Sounds like the drive chain/belt in the transfer case isnt engaging it could either be broken not being engaged due to solenoid not working. check these things then get back to me.

I have a 1994 k1500 6.5l turbo diesel and every time I put it into 4hi my truck goes about two feet then I hear a loud clunk and the truck feels as though it is going over a speedbump in the front because...


Wow. A snapped side shaft sounds serious. If you lift the front end of the truck, (or the rear end for that matter) the wheels will appear to be counter rotating, it is the way a differential works. If you turn the left wheel forward, the right wheel will turn backwards, and vice versa.
When you change to 4wd the front end does make a rather loud clunking sound as the gears engage. You should therefore change while the truck is stationary, then slowly move forward or back until the 4wd engages, then take off.
If your truck went OK on ice, it should go as well on pavement, just don't try to engage 4x4 while moving.

Humming noise coming from transmission when its in neutral. push the clutch in and it stops. suppose to be a new clutch also it runs great but if you lift the rear end off the ground the wheels will s


A noise in neutral that goes when the clutch is disengaged indicates a front input shaft bearing in the gear box . When the clutch is out that shaft is spinning along with the cluster shaft in the gear box. When the clutch is in that shaft stops (to engage first gear) and the bearing is no longer working.. It normally means a box out job.

The Selectable Four Wheel Drive (S4WD) Front Axle consist of the following components:
• Differential Carrier Housing
• Differential Case Assembly
• Inner Axle Shaft
• Intermediate Shaft Bearing Assembly (located on the right side of the oil pan)
• Electric Motor Actuator
The front axle on Selectable Four Wheel Drive (S4WD) model vehicles uses a disconnect feature mounted on the right side of the oil pan in order to engage and disengage the front axle. When the driver engages the 4WD system, the Transfer Case Control Module sends a signal to the electric motor actuator to energize and extend the plunger inside. The extended plunger moves the clutch fork and clutch fork sleeve across from the clutch fork outer gear that is splined to the right side wheel drive shaft to the clutch fork inner gear that is splined to the inner axle shaft. The locking of the two gears allows the axle to operate in the same manner as a semi-floating rear axle. A propeller shaft connects the transfer case to the front axle. The differential carrier assembly uses a conventional ring and pinion gear set to transmit the driving force of the engine to the wheels. The open differential allows the wheels to turn at different rates of speed while the axle continues to transmit the driving force. This prevents tire scuffing when going around corners and premature wear on internal axle parts. The ring and pinion set and the differential are contained within the carrier. The axle identification number is located on top of the differential carrier assembly or on a label on the bottom of the right half of differential carrier assembly. The wheel drive shafts are completely flexible assemblies consisting of inner and outer constant velocity CV joints protected by thermoplastic boots and connected by a wheel drive shaft.

The car can be put in gear, but the gears do not engage, it just revs. Manual transmission.


First I would ask if this is a "new" problem. Then I would ask is the front wheel or rear wheel drive? if rear wheel drive, is the drive shaft turning if so then Rear end or axial issue. if not then try all the gears if any other engage (especially high gear) then transmission problem.

  1. Use a small cape chisel to carefully raise the staked portion of the front axle wheel hub retainer (3B477).




  1. Remove the front axle wheel hub retainer and discard it.
  1. Remove the cotter pin and the tie rod end nut from the tie rod end (3A130). Discard the cotter pin.




  1. Use an appropriate tie rod end remover to separate the tie rod end from the front wheel knuckle (3K186).




  1. Remove the ball joint bolt and the ball joint bolt nut.




  1. Carefully pry down on the front suspension lower arm (3078) to separate the front suspension lower arm ball joint (3050) from the front wheel knuckle.




  1. Pull outward on the front wheel knuckle (3K185). Carefully pull the front wheel driveshaft and joint from the front wheel knuckle and position it aside.




  1. NOTE: Removal of the LH front wheel driveshaft and joint (3B437) requires removal of the transmission support crossmember (6A023) to allow access with a pry bar. If the LH front wheel driveshaft and joint is being removed, continue with step 11. If the RH front wheel driveshaft and joint is being removed, continue with step 15.

    Support the transaxle with a transaxle jack or equivalent.
  1. Remove the four transaxle mount-to-rear engine support nuts.




  1. Remove the two rear engine support nuts at the rear of the transmission support crossmember.

If the gears become misaligned, the differential will have to be removed from the transaxle to align the gears.
    If both front wheel driveshaft and joints were removed, install Transaxle Plugs T88C-7025-AH in the differential side gears.
  1. Remove and discard the driveshaft bearing retainer circlip (3Z498).
