Can you record it? Probably a failing relay/actuator.

 

Could be mount bushings going bad If it only does it at those times. Open the hood, make the shifts and watch or record what the engine/Trans is doing.

I think he has an auto bigbird..

 

I know, it says it in the title. I've owned almost more autos than manuals. The diagnosis still applies, maybe even more so. Happened to 2 of my old cars.

Will try to record it. I also need to crawl under the car & check the transmission mount... hoping it's something minor.

 

Here is a video recording of the noise coming from engine bay after shifting gears. This is recorded from the inside of the car. Initial noise is me moving the shifter but right after is the crackling/knocking sound. I am incline to believe it's the transmission mount or even my intake or ORHP hitting something as the engine flexes when the gear is changed. Will need to go under the car & investigate.

 

I'd check the lower engine mount to make sure the bushings aren't shot. Also make sure the bell housing bolts are snug. Other possibility is the axle nuts being slightly loose and when you put it in gear it puts a small loud on them and then relax when off.

 

Was thinking maybe it's the axle nut/axle bearing also.... if I put it in gear and turn the wheel then drive off, I hear it (especially when reversing during parallel parking)

 

Pretty common issue, axle nuts.

 

Thanks Mr.Robot. Will check out it this afternoon after work... hope it's as simple as that.
Will hit you up later tonite about something I am working on (if I don't go out drinking again, my cuz & brother want to hang out tonite)

 

I had a problem with my transmission about two months ago. Not wanting to shift and made all kinds of noises. Hyundai replaced a gear shift actuator and all was well for a month. The past week or so I've been getting the exact noise you are getting, except I only hear it when coming to a stop, rather than changing from park to drive. I thought it was the same deal I had previously except not as severe. Not sure if the problems are related, but the sound is an exact match. Best of luck with the axle nuts, I'd be thrilled if it was that and not something to do with the transmission itself. I'm scheduled for normal maintenance on Friday, I'll try to show them the noise and get their opinion as well. I'll get back with any other information they give me.

 

Happy to report noise is gone... turns out to be the axle nuts. When I removed the wheel, the bent part of the nut was still in the slot. After I bent it up, it didn't take a lot of torque to undo the nut. I thought I would need a breaker bar but that wasn't the case. After I re-torque the nut, the original bent part was pass the slot, so it looks like there was some play on the axle. Will monitor it for a few days to see if noise returns. Thanks everyone!

 

Darkness thank you so much for doing the video. I've stumped everyone with this issue on my V and finally the wording combo in my search hit both your post and a technical service bulletin for Elantras and the washers behind the hub. After seeing your video I'm going to buy the washers, re-torque it and see where it gets me. Finding a video with the same sound and issue was starting to seem impossible.
