ok so my fj62 has a little issue. I was planning on driving it up for the annual meeting saturday, but i think i'll be coming cruiser-less. The problem is a grinding sort of noise when i go above 55 mph. The noise increases in intensity with increased speed, and it is also worse as i let off the gas after acceleration. yesterday i changed out the fluids in the rear end and the T-case. I was hoping this would fix or help the problem , but it has not. I do not believe the noise is RPM related because when i took it out yesterday after changing the fluids, I drove it in gear 3 for a while and it started making the noise at 55mph just as it does when the cruiser is in drive. So heres my question. I dont have a lot of money so before i go and spend it on a rear end rebuild kit, I was wondering what you all thought. Is the grinding noise in my rear end or is it somewhere else? Also, is there anything else i can do to diagnose the problem? your input and help is much appreciated.
