Hey, we recently bought a 2016 Toyota 4runner sr5 2 years ago and put on 90000km and had some common issues but its been pretty good. Recently there's been this hum, maybe sounding from the front above speeds of 55 that seem to go away in 4wd. We took it to a mechanic and they inspected the drivetrain and couldn't find anything. I'm taking it to an actual dealer out of town next week. Any ideas?
It could be a lot of things. Things like worn universal joints or loose suspension parts, for example, even tires. That vehicle isn't all that old, it would be unusual for that differential to be worn out after just 8 years. (Anything is possible of course but I have cars over 50 years old where the original diff is still good!) I'd get another opinion from a good independent shop. (Not a dealer or chain.)
Other than that, is the truck still stock or has it been lifted, aftermarket wheels installed, or any chassis modifications done?
It's completely stock bought used 2 years ago at 79000km. In 2 years it's now at 150000 and it started making tire noise when the old ones started balding. I believe the front were bolding on the inside faster than the out. Once I switch to new tires the noise consisted and maybe a little bit worse. It's weird it goes away in 4x4 though. I heard it's usually the needle bearing if that happens but it sounds as if it's the right side and only the left has a needle bearing
Could a bad diff make it seem like a driveshaft vibration? I'm putting it up on jack stands and getting a friend to drive it while I try and listen. Thanks for the video
a worn out pinion bearing could, yes.
Well sounds like some kind of bearing a drive shaft noise. See my video finding the source of car noises Scotty. It's on YouTube and that machine can find the source of any noise
After taking his 2016 4runner sr5(150000km) into shop they discovered that the front diff is blown. My dad owns this and drives it very slow and bought it well maintained with 80000km and has put on highway km for 80% of it over 2 years. It seems unreasonable for the diff to already be gone with the humming getting worse. They quoted 2000us from the dealer for the part and probably another 1000 for labor. Should I drive it 4hrs to the dealer or get part numbers and order it oem?
The him goes away in 4wd and it sounds like a needle bearing. There's this company that makes a replacement that's a pull peice of metal that's supposed to be stronger but if the needle bearing broke should I replace the whole diff?

Yeah they should last longer than that but realize quality control isn't what it used to be and realize that that differential is generally not even made by Toyota. They buy from a second party and I'm assuming their second party guys aren't doing the job they used to do
Yeah I'm sorry to hear that. I'm a strong believer in that too I bought a 2000 4runner and mine now has over 400000km with barely any work. The proof is in the pudding
Looking for some help here. my 2016 4runner still has a vibration going above 50km sounding from the front passenger that goes away after switching into 4wd. Seems to have quiet down for a day and comes back the next. after taking it to a shop in my town they deemed a full front diff replacement quoting 2400 for the parts. Obviously unreasonable I took it out of town to the dealership and they deemed I needed an entire new rear diff quoting 4000. Not really many options here, what do you think it could be?
We've had this truck for 2 years now and bought it at 79000km, now has 150000. There's a vibration in 2wd, worst at 60kmph. It quiets down at highway speeds. I took it to a small shop in my town and was told I need a new front diff. I took it to the Toyota dealer out of town and they said I need a new rear diff and when I talked to the technician he said using microphones he heard a sound from the rear diff and the binding transfers through the driveline and causes sound in the front diff. The sound comes from the front passenger side so it sounds a bit alarming. I would like to get an opinion from you before I spend 4000 on this. Should I change the fluid and look for metal or anything I could do to confirm? I'm taking it to yet another shop in town in the next few days, thanks
