2004 Toyota Tacoma
What is that thing thats bolted to the left side of my transfer case? It almost looks like a weight. Whats this for?
So if i take this off then i will have noise issues?vibrations are a function of force and mass. if you change one, the vibrational frequency changes. manufacturers use the weights to change the harmonic frequencies of parts to not match. Chevy had a problem in the mid-80s suburbans that a harmonic happened in trucks with AC, I forget which trans, and 3.58 rear end. about 55 mph the AC compressor (harrison R4) and trans oil pump lined up harmonics and the whole truck resonated. the next year all the trucks had 3.73s (to move the vibration to 75+) and a redesigned trans oil pump
Maybe. Depends on what exactly was vibrating, when, and how bad. If it's just bolted on, you can always take it off and see if it bothers you. could be a hum, whine, vibration...anything. maybe it only happens at 5 mph, maybe only at 85, maybe every time the engine is at 2k rpm, maybe 6k. only way to find out is to ask the engineer that put it there or try taking it off.So if i take this off then i will have noise issues?
Actually noises are vibrations that fall in the audible frequency range. Mass dampers like the one found on the transfer case are just as likely to be there to reduce audible vibrations as felt ones, Maybe more so.It's there to counteract vibrations, not reduce noise.
