Worn inner CV joints can cause vibration, where worn outer joints are more known for clicking on a tight turn.

Your situation reminds me of what sometimes happens after a 2" lift kit is installed and the angles on the inner joints are changed / increased.

You can try checking the inner joints for grease leaks and see if they have excessive play:

 

thank you @Sandstone for the response so I just went out and checked the axles and passenger side is solid as a rock no leaks no play. Driver side has the most (minimal) amount of play i mean ALMOST nothing and no leaks. Would you still lean towards the fact that it could be the culprit? also to reinnerate the suspension that went on was strictly oem replacements no lift kit or anything that would warrant the angles to be out of wack froma spec standpoint. Thanks in advance for any other responses or ideas

 

What I was getting at is the change in angle from where the joint was running to where it is now, like after you add a lift.
With old, sagging springs the axle sits in more of a straight line; the new suspension parts act like adding a lift, raising the car 2" from where it was and increasing the angle.

In the vid below, he shows the excessive play due to worn needle bearings around 3:22, and talks about how the play changes the rotation pattern of the axle from circular to off-center / wobble-ish which causes the vibration.

You could ask the mechanic if they could put it on a lift and run it to see if they can nail it down.

 

Did you ever found what the issue was, am having the same specific issues with my 2019 Corolla

 

I hate to say it but at this stage in the game I believe that it's something with the transmission. I had replaced the CV axles all suspension and anything else that could correlate with it and nothing ever changed about it.

 

Thats what i was starting to think too And everytime i bring it back to the dealership they are telling me the transmission is fine...am going to have to take it somewhere else

 

It's hard to say because of the fact of you having a different car. I know everything that I've put into my vehicle since owning it and there would be nothing else left to do that would cause that issue. If your car has low miles and is newer I would like to think that it's not the transmission. But unfortunately nobody's really going to be able to diagnose the issue unless I check engine light comes on. I guess I would tell you to go to a transmission shop that is very well known in your area and let them take it for a drive

 

Did you ever figure out what was causing the problem. I replaced both front lower control arms wheel bearings and CV axles july of 2022 then six months later got are rotational vibration at about 15 to 20 mph CV axles look good no tears or leaks not a lot of play eithet

 

I have literally replaced all suspension components, no change. I have checked all motor mounts, trans mounts and bushings etc.... No change.Cv axles and wioth the new upgraded passenger side 1 piece axle no change. I even had a priest shake holy water on it no change. I brought it to an actual Jeep tech and had him drive it and his opinion was that it is the trans I also had two other mechanics I personally know check it out and they came to the same conclusion .The cvt I guess is notorious for issues. I drained and replaced the trans fluid which did help get rid of a whiny noise i had while accelerating and maybe the vibration became a smidge less noticable however it is still there trnas also overheated 5 times while making a 3 hour drive in summer last year as well. I will say this is the absolutely worse vehicle i have ever owned in 30 years. its a shame because I do like driving the vehicle but I will never own another jeep product in my life. I have done nothing but chase issues for 3 years. I just wrapped up repairs with replacing the oil pan seal as well a fixing a coolant leak and then a week later replacing the crankshaft seal because oil was pissing out all over my driveway. Between those three leaks my driveway looks like i just stood there and poured quats of oil and collant all over. I am driving this thing til it explodes or I ghost ride it off a cliff. Hope this helps. My honest opinion is that if youre in a position to sell it get rid of it ASAP. oh and keep in mind my jeep on has 120k and all of these issues started at 90k

 

I agree it was good car up till about 90K. I have the 6speed transmussio n. Then its been one thing after another the problem I have I have 3 pats all my kids drive one this is the highest milage one. Thanks for reply if I figure it out I will post fix

 

Yea h good luck , I was really convince it was the cv axles but after I did all of that stil no change. Bummer really

 

I ThinkI found the problem u joint on drive shaft was frozen. one axis was free other axis lockedup. Ordered new drive shaft don't.know if old one can.be rebuilt will.post results when new shaft is put in.

 

good luck to you I wish it could have been my problem because atleast I would have a definitive answer. However my interior driver side door handle just snapped so now I have a new project hahaha. Good luck to ya

 

I'm suspecting the drive shaft, if the front U joint is loose or the center support bearing is not good they cause this kind of vibration .Good luck

 

Yes it was a driveshaft front ujoint that frose up on one of its axis
