JB74 Rattling noise driving me crazy.

Not sure if this will also apply to your case but i also same problem with my JB74 2020 (all stock fitted with bf goodrich ko2). Rattling sounds when driving over bumpy roads and the sound seems to be coming from the rear door. I did everything (removed spare tire, dismantled the rear door panel and lubricated everything with WD40, sound foam and sound deadening all over) but with no avail.

But just today i found that the sound was not coming from the rear door but under the car. The culprit was just the wire or hose found over the right-rear suspension dampener. It was apparently hitting the chassis or frame of the car when driving over bumpy roads. I just bent it a bit since its attached to a thin metal frame so that it would not rattle or hit the frame. Problem solved. Try to look into this one might be the same as yours.

Hello guys
i m new on this blog and i don’t find exactly how post a new problem so i found this way to tell you about my issue. 

well, i have a vibrating sound in the back door of my jimny jb74. I tried to locate the exact place but couldn’t …. 
I had that black wheel cover i thought it was the reason but the sound is still there after taking it off.

howewer, when i « punch » the back wheel i hear that annoying sound and trust me it drives me crazy. Sometimes i feel like the back door glass is vibrating, sometimes i feel there is something inside… 
so i wanted to ask you guys if u have ever faced the same issue ? 
what is the solution? 
any guess ? 


thanks for helping me out 

Have you checked the tightness if the spare wheel nuts to make sure it is held securely? if they are tight, remove the spare wheel and check the wheel mount itself is secured properly.

On my LC, Toyota had fitted a small block of rubber that was fixed in such a way as to support the wheel at it's edge. This helped to prevent flexing of the back door, especially with my 33" spare wheel.

i have the same issue. İ took off the plastic inner panel and then hold cables, parts inside with my left hand and keep punching the spare wheel with my other hand to locate the rattle source. But it never goes away. I think they might skip a part of the insulation between metal panels where they welded together. İ will try again hope i will find it. Emir

Have you tried thin rubber washers behind the spare wheel mount between the mount and the door? THere were some made at some point without 77151-82000 seal in place
