1st short video was recorded a while back when it was on a extremely cold morning here in GA ( unusually cold for during winter months)
2nd short video was recorded this morning 2/15/25 - not very cold this on start up ..just misty rain and probably about 45°
Now…I have been having a vibration/grinding noise for a while. The vibration/grinding noise is a rotational issue.
It is felt ( besides hearing what I have recorded on video) then I put in drive ( jeep is on pavement) at idle..(no gas pedal being used at this time) just engine rpm and transmission moving Jeep forward..very slow..I can feel that moving forward slow at idle rpm..like I have a flat spot or two on a bearing, however it continues as speed increases and I can feel vibration/grinding at any speed above about 20 mph..in the front tub area, front seats and when I put my hand on very top of front right/left headrests.i feel the vibration/grinding there ( kinda weird). I also can feel it while driving and put transmission in “ N “ and when coming to a complete stop..I feel and hear ( I’ll try to describe) a different vibration/grinding sound ( kinda weird also).
I have had all wheel bearings replaced, including rear axle bearings. I have had a rear differential total rebuild professionally by a local business that’s been in business for over 50 years. The owner of the business was the one who actually did the work himself. He’s a great guy and has a lot of knowledge been working on jeeps for more than 50 years.
Once I received the Jeep back from the mechanic shop, I put the triple meter back to 0 so I can keep track of how many miles is actually on the newly totally 100% rebuilt rear differential which included new axles also they were badly damaged too.
I have been back to the shop several times with this issue that I’m having and the mechanic who did the work thinks it could be an issue with the type of tires that I have on this Jeep Which have big lugs kind of more of a muddying type tire. The mechanic also told me that he wanted me to take him for a ride and I did and it’s really hard to pinpoint exactly where this issue is coming from and that’s why he still thinks but not 100% sure that it could be the tires.
In my personal opinion since I drive this Jeep every day of the week 3 to 500 miles a week that this issue is possibly coming from somewhere else other than the tires. I’m starting to wonder if it is something in the automatic transmission or in the transfer case or front card an joint or transmission, torque converter, or output shaft bearing… the owner of the shop, checked everything out really good and said you joints were tight. He checked fluid in the transfer case checked to other items also while he had it there to shop doing a total rear differential rebuild.
Right now, I can say that driving this Jeep with the vibration and the grinding issue is driving me nuts and I’m hoping to figure out where this issue is coming from and get it fixed so I can actually enjoy driving this new to me Jeep, which I haven’t been able to do yet.
The mechanic told me that unless it gets worse and it’s some sort of a mechanical issue somewhere else that that is, that would be a problem. He seems to still think it’s the tires..
The tires are not really that old. I’ve had them rebalanced rotated and still have the same issue.
If you need any more information to help me resolve this issue, I will gladly add it to this thread.
I do know that once it stopped raining here in Georgia. I’m gonna jack up the entire Jeep. Get the tires off the ground put the axles on. Jack stands front and back gonna do this safely then put it in gear. Let it idle and drive which is 2 Wheel Dr. 1st see if I can fill anything or hear anything then move up to four-wheel-drive high and see if I can fill anything or hear anything. I’ll be damn if I’m gonna let this thing whoop me.

…is that a crack at the right bottom of the weld at the ring gear?
