Question about 2005 Jeep Grand Cherokee

1 Answer

I have a 2005 3.7l jeep grand cherokee. I just wanna know what bolts I need to remove to clean out the front differential. How many there are. I already did the rear. That was easy. Does the front need to be cleaned at all or could I just add new oil?

    Can I do a real damage? So I just take the bolts that go around the cover? And clean the inside and refill with diff fluid? Is it pretty easy like the rear one? Thanks for taking the time to help. I love leaarning about cars and I wanna be a mechanic one day.

    Im gonna try doin it. Hopefully I don't mess anything up. Im kinda learning as I go. The mechanic was gonna charge me 230 to do the front and rear. I don't have that kind of money. Im just a kid. I spent 90 dollars on everything I needed. Ill let you know how it goes. Hopefully I don't make it worse. And yes I already did the transfer case.

  • It's just some bolts holding the cover plate to the front pumpkin (differential). 10 maybe. You will need a cover plate gasket if you pull the cover plate. You can drain and fill it if you want and it will be fine. Being a mechanic I always like to pull the cover plate and spray the spider gears with some brake clean first then put the cover plate on and fill it up. Get's them gears squeaky clean. But a simple drain and fill is sufficient.

    Im doin it for the first time at 95000 miles. I cleaned the rear with some brake part cleaner should I use it on the front diff also?

    1. Yea, I would. 95,000 miles is a lot to put on that front differential without a change. I'd inspect them gears good while in there. I would pull the plugs as well and clean them too. They are magnetic tip and made to pick up metal shavings should they occur. Don't want that getting into a freshly cleaned pumpkin. Use 75/90 gear lube too.

    Change the transfer case fluid every 50,000 miles too. Hope this helps you out.

    So take the bolts around the cover off and will it come off? Then clean the inside of it with brake part cleaner. Would I use rtv gasket for front one also? Thanks for taking the time to help me out. I love learning about cars and hope to be a mechanic one day

    • That's great to hear you want to be a mechanic. It sure puts some weight into the wallet that's for sure. And when you build your first car that goes vertical when you punch it and your stomache drops because you can't steer it until the front wheels hit the ground again your adrenaline rush will keep you awake all night lol.

    • Yea you do it just like the rear diff. You did scrape the old gasket off the rear and put a new one on didn't you? Just making sure because you need to do that if you have not. And use a new cover plate gasket for the front too.

    • Anytime you have questions you can click my name and click "ask me" and I should get it.

    No, I don't recommend rtv. I recommend neoprene. RTV is not chemical resistant. It will rot eventually. Use OEM or cork and neoprene.

    • Yea, it can cost to get those done at a shop. You'll be fine.

Remove front Rotors


To remove the front rotors,you first need to support the vehicle with a jack stand.Then remove the wheel.
Once the wheel is out of the way you need to take the two bolts off of the backside of the caliper, then compress the caliper and lift it off of the rotor.
Now you should be able to easily remove the rotor from the Jeep.

Just had my 1999 jeep grand cherokee front differental (dana 30 3:73 ) replaced at a cost of $900 ,noticed the front cover was never totched (dirt on bolts) . CAN THIS TASK BE PERFORMED without removing...


Yes. The front differential can be changed without opening the front cover. I'd say it looks like a used differential was obtained and installed. The differential (assembly) is the entire front assembly housing the axles. If an axle were to be changed then the differential cover would have had to be removed to access the components.

I just find it somewhat unusual that the cover was not taken off by the part supplier to inspect the integrity of the pinion gears etc... I remove used parts nine hours per day, and unless I know for a fact that the (front) rear is good, I take the cover off to inspect it for wear and/or potential damage. In this regard, it may have been one of those instances. Check the bolts on the trailing arms (the bolts on the arms that lead to the frame) and other bolts to see if they've been disturbed, if you suspect foul play.

1995 Jeep Grand Cherokee with fulltime 4wd and only turns rear!


You know for a fact no power is being sent to the front axle? This transfer case only sends power to the front axle when the rear axle is slipping. Are there any unusual noises in the front axle?

If it is the transfer case, replacing it is not too big of a deal. If you are the least bit confident of your abilities, then you can do it yourself. I believe you have the NP242 transfer case, but I could be wrong. There will be a tag on the back side of the case, facing the rear axle, to the left of the drive shaft. On that tag, it will tell you which case you have. You can either have yours rebuilt, or buy a replacement either new or used.

To remove the t-case, first drain the fluid. Next remove the front driveshaft by removing the four bolts holding the u-joint in place. Then remove the rear drive shaft by doing the same as the front driveshaft, only this time it's at the rear differential. Once the drive shaft is free, support the full weight of the driveshaft, not that heavy, and pull it out of the t-case and set aside. Disconnect the shifter linkage and wiring harness. Next, remove the bolts that connect the t-case to the t-case cross member. Lift slightly and support the tranny/t-case assembly and remove the cross member. The t-case isn't very heavy, but you don't want it falling on your head, so remember to support it as you remove the bolts that connect it to the rear of the tranny. Once you bring it out from under the Jeep, and it's rebuilt or you have another unit to replace it, installation is the reverse of removal. Just remember to refill the t-case with the proper fluid.

The 99 Jeep Grand Cherokee was prone to bad diff bearings because they changed the plant where they were made. The new plant used inferior materials. The only way to fix it is to replace and set the diff clearences.
