Many rocklobsters make more noise than the standard Jimny t-box. This because they are usually made of welded used SJ410/413 gears.

Wow mine is nothing like that at all! Mine is definatly wining but no we're near that bad! What speed are you doing when it's that bad?

its been built for me new seams to wine all the way through the speed range didnt seem to be that badd in 4 wheel drive but i mite have just not noticed

You get what you pay for! Cheapish price comes with some whine...

Welded gears are always whiny, and even a stock SJ box is considerably noisier than a Jimny's box which is pretty much silent. I have 6.5 Trail gear reduction gears, and those whine some too, but it's almost silent compared to some welded gears I've seen/heard, and it mostly whines just when I engine brake in small gears.

Get some billet cut gears if you don't like the noise, because it's pretty much there to stay!

I think it is worse on engine braking drove it to work this morning and its not to bad just a lot worse than im used to mainly used offroad so wont notice wile having fun found the vibration reason shafts not straight have to redo that properly can the coupling on diff just be pulled off
