If you are talking about the Splined Disconnect, that is on the passenger side of the differential and is known for running dry and self distructing. Yes, it can be removed separately and replaced or repaired without any other disassembly. Below is a figure of parts of the front drive system.

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.

SOURCE: My front differential is leaking!

neither of the previous solutions are coming from ppl who know what they are talking about. i am in the process of making this exact repair, on the same front differential. you have to un-bolt the cv from the axle shaft, then drop the front diff. the passenger side is easier to deal with than the driver side from what i'm experiencing. once you remove the axle tube from the passenger side it is very simple to dissassemble and replace seals and bearings. the drivers side however is a different story. there is a lock ring that holds the axle shaft into the diff on the drivers side, and i have yet to get to it to remove the axle shaft. once the axle shaft is removed, then you just pry out the seal and carefully tap a new seal in its place. reassembly is the opposite of disassembly. if you find out how to remove the axle shaft snap ring, please let me know. hope this helps

I have an intermittant grinding on the front of my 2000 Kia when I go over bumps. the wheel bearings were already replaced because of this, but the grinding continues.


It seems as though you have changed everything.

A grinding noise is associated with something turning or rubbing against something. The only other thing that springs to mind are the drive shafts, which have splined ends. The link below will show you generic images of driveshafts
kia drive joints Google Search

Each end of the drive shaft is splined. One end fits into the gearbox and the other end attaches to the road hub of the road wheel.

It's usually the hub (universal joint that allows the wheel to turn)/ wheel end of the drive shaft that wears. It may be that the grinding noise has been more pronounced when turning? And the grinding noise is coming from just one side?

A new drive shaft isn't cheap although second hand ones are readily available. replacing a driveshaft isn't a particularly difficult job.

However, it may be an idea to get somebody to remove the brake calliper/rotor/ driveshaft hub and inspect the hub/splined end of the drivehaft. What you're looking for is worn, broken or chipped splines. If all seems okay try cleaning and repacking with driveshaft grease. It's probably the hub - the bit that allows the wheel to turn - as opposed to the splines -there's bearings inside that hub (also known as a universal joint). There's no real way of examining that hub other than replacing the driveshaft

Tractor case 585xl front diff not driving. Front shaft drives but not wheels.



I am thinking that you have a broken/ stripped drive spline on a front axle. If you have reduction gears in the hubs , it may be stripped teeth on a gear. If you jack up one front wheel and turn the drive shaft that wheel should turn. IF so repeat the procedure for the other wheel and if it doesn't turn like the other side then that is the side with the problem

How to remove1995 cavalier transmission


The transmission is transversely mounted in these vehicles. The mount that secures the transmission to the body is also supporting the engine. If you want to remove the transmission without also removing the engine you will have to support the engine once you remove the transmission mount. You will need to remove the drivers side wheel, caliper, and rotor. You then need to remove the drivers side CV shaft. You will need to separate the lower ball joint in order to remove the shaft and to provide working room to separate the transmission from the engine. You need to disconnect the Shift cable (automatic) or slave cylinder (manual) from the transmission. You must separate the passengers side CV shaft from the transmission, but you do not need to full y remove it. Ensure that you do not separate the inner CV joint when pulling the transmission free from the inner splines. Remove the flywheel shield plate. If automatic transmission, unbolt the torque converter from the flywheel. Disconnect any electrical connections from the transmission. If automatic transmission, disconnect the hydraulic lines running to the radiator. Unbolt the transmission from the engine at the bell housing. Automatic transmissions will come out fairly easy...manuals you must pull back to disengage the transmission splines from the clutch disc.

Front end grinding


The end of the drive axle that goes into the diff is in splined into the side gear of the diff and will be dry as there would be no way to stop the oil coming out of the diff past the splines. The diff seal runs on the outside of the side gear and seals the oil in the diff. The drive axle slides in and out of the splined section to compensate for the changing lengths of the axle on turns. Grease on the splines would be a big help as it would allow the splines to move when under drive load.. Check the hub bearings for condition and adjustment and check the hub itself for wear indicators.

2003 gmc envoy 4x4 problems. 4200 vortec engine. my front diff doesnt seem to be


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.

Loud knocking sound from front drive axle side


I really doubt that its the spider gears that are bad. Most likely that its the axle shaft- not as bad as it sounds- I sell lots of them.
