2013 825i with 400 hours, 5000 miles. Im noticing the front wheels feel like they are dragging. Almost to the point where they want to slide on the gravel and make the rear tires spin a little. Doesn't seem to make any difference with the 4x4 switch on or off. The weird thing is in reverse it seems to drive smooth with no binding/dragging. Does this sound like a front differential problem? Does the driveshaft to the front end spin constantly and 4x4 is controlled by an actuator on the diff itself? Thanks!

There is a coupler at rear, right side near park brake . You will need to take the Alternator belt cover off .Take the torx screw out slide coupler over . Also one near front near front diff. There are 2 bearings on pillar blocks. and cv joints that could be bad.

Tyler: The exact same thing happened to me last Friday with my 2011 - similar miles and hours !! No prior warning or evidence of trouble and bam !! Do me a huge favor and take notes inc.p/n's and keep us posted. It sounds like the local dealer would finance a year of his kid;s college tuition with this one so I may try to find an Indie. Thanks much. Craig

I have a 2013 825I, about 600 hours, second owner, with similar problems. The left front wheel skidded intermitantly mostly when going down a 6% grade. Eventually, that skidding destroyed the CV joint. That skidding ocurred when the air temperatures were 80 degrees or more. Also, it made no difference if the 4WD selector was in 2WD or 4WD. I would stop, backup 20 feet, restart with some success. Keeping a constant speed helps. This wedging is a common Gator problem.

Upon replacement of the CV shaft, no oil came out of the front differential when the shaft was removed. Removing the drain plug showed the front differential was dry.

Replacement of the CV shaft and lubrication did not completely solve the problem. I considered a dragging brake pad to contribute to the problem. I have yet to install new ball joints.

So, I am still working on the problem. I am also working on other PROBLEMS.

Hope this helps.

Gators have a known habit in which one or two of the front wheels grab. It has to do when shifting out of 4WD while going downhill while engine braking. The splines don't properly release and can hang up. Fix is to put it back into 4WD and go quickly in reverse for about 20 feet. Stop and then put it back into 2WD. Ease forward to confirm the splines have cleared back.

CaptSeabee, with what you said, I would assume there are no real fixes then? 2013 825i with the same issue.

Inside the front diff there is a plastic "rack" that holds 12-14 rollers. They are know for the rollers detonating causing them to split in half and doing serious damage inside the diff. The main ring gear inside the diff has a large bearing that seems to bear the grunt of it in my experience. The rollers are 240.00 to replace as long as the rack that holds them is still in tack. The diff is very straight forward to take apart to inspect bearing damage.

I've had a couple 825i's in the shop with this problem. In my experience, the roller cage in the front differential was cracked or broken, so the engagement rollers were not held symmetrically like they need to be. This allows the rollers to wedge and lock the drive line which causes the wheel drag. If this is addressed quickly, you can simply replace the roller cage and rollers to resolve the issue. The rollers themselves will get grooved and can eventually shatter if the customer continues to drive the machine much after the roller cage fails. If driven long enough, other components can also sustain damage. Here's a couple of pics from the last one I did for anyone who has this issue and wants a preview. This one required a new cage and all new rollers.

A few years ago I replaced the “sprague” carrier in my 825.
The process was rather tedious when trying to insert the rollers bearings and tension clips back into the new sprague carrier.

I will be this weekend. Just looking ahead to see if there is something specific to look for. Was hoping it might be a common problem with a common solution.

When it does it , its in 2wd and usually after driving on the road for a while. It seems to vibrate the front end and sounds horrible more so on drivers side but hard to tell. I switched to 4wd and then switched back to 2wd and back up a little bit and it seemed to help.But that is not a solution...lol

The sprague carrier that is shown in photos above may be the culprit. There are certain times when a wedging condition in the front differential can occur, generally when you flip the 4wd to 2wd switch and back up, the carrier bearing will re center itself which what you maybe experiencing after backing up. Have you checked the front differential fluid ?

It will be the first thing I check Do you know what type oil it takes by chance? And where do you check it at?

Without knowing the Product Identification Number or PIN of your 825i I can’t point you to the exact Operators Manual for your Gator, however Deere recommends the use of HYGuard in their equipment. Depending on the temperature where you operate the Gator, you may want to consider using their low viscosity type of HYGuard.
