If it's a limited slip differential then the differential needs an additive. I'm sorry I don't know what it's called, but it's very awful smelling stuff! Any auto parts store should know what you are talking about.
There wasn't a 2003 Cherokee. The last Cherokee was 2000.
Need a new gearbox. You get a grinding noise only in first gear when you accelerate fast . second gear and the rest should be fine.
Gearbox oil needs changing.
Most motorcyles have a liguid clutch which means they run in motor oil so when you change your motor oil you are changing your (gearbox) transmission oil and to check your (gearbox) transmission oil level you check the motor oil level.
Gearboxes on trucks are generally not synchromesh. It means there is no mechanism to automatically adjust the speed of the engine and the gearbox to match. Therefore if we would simply change gears like in the modern passenger car equipped with the synchromesh gearbox by depressing the clutch and shifting the gear up or down before releasing the clutch the different speeds of the engine and the gearbox would cause the grinding. To avoid this change requires process called double clutch. It goes like this: 1. Depress the clutch, 2. Shift the gear into neutral, 3. Release the clutch, 4. If shifting down depress the accelerator to rev up the engine so the rpm's of the engine are slightly higher than the gearbox and release it; if shifting down depressing the accelerator may not be necessary if the whole process is done quickly enough, 5. Depress the clutch again - that's why it is called double clutch, 6. Shift the gearbox into next gear (up or down). At this stage the rpm's of the engine will be slightly higher than the gearbox and the engine will be slowing down at some point the speed of the engine and the gearbox will match and the gear will go in without grinding. This needs to be done with the feel and with the bit of practice it becomes automatic. The amount the engine needs to be speeded up will depend on the conditions for example if changing gears when going up the hill.
If it is done right without grinding the gears, nothing. You need to take the load off the gearbox, by lifting of the gas slightly, when changing up. Pause in neutral before easing the next gear in. Changing down is harder to do smoothly. Lift off the gas, pause in neutral, increase the revs to what you think it should be, for the speed in the next gear. Ease the stick into the next gear down.
Harsh ShiftingTwo causes immediately come to mind, although there may be others:The clutch is not properly adjusted and doesn't fully disengage.The gear "synchronizers" inside the gearbox are wearing out.
An automatic gearbox is maintained to keep it serviceable for a long time by changing the fluid and filters at regular intervals. The entire system should also be flushed periodically to remove contaminants.
There are a few reasons for this. First the bearing in the gear box may be dry and need grease and the other issue may be the linkage is broken.
The clutch of a go kart is much the same as the clutch on a car. The clutch disengages the engine from the gearbox enabling the gear to be changed. Without a clutch gear changing would be difficult and may damage the gearbox.
if this vehicle has a standard gearbox, i would have the clutch looked at.other problem could be water pump is about to fail
Sounds like the diff in the gearbox is goind and will need the whole gearbox replacing soon before it fails completely.
