noisy cab? - Pirate4x4.Com : 4x4 and Off-Road Forum

bashed4runner · 01-10-2002, 07:27 AM

At freeway speeds(50-75mph) I have a noise in the cab of my 95 disco that sounds like bad aerodynamics but in the back of my head I think it could be maybe a wheel bearing or somthing of that sort. So I guess my Q. is this common or is ther somthing shot in the front end. give me what you got, thanks

How many miles on her?
When was the last time all the wheel bearings where adjusted and lubed?

We need some info: Miles, mods, do you wheel it?

I know one problem can definitely be wheel bearings. Is this a new onset sound? They do always make noises from the t-case due to the straight cut gears.

Also, sometimes the t-case gets noisier when the rear driveline angles are too great for the u-joint on lifted rigs. Or.. the driveline u-joints could be going bad, causing resonance in the t-case. I'm not sure if you have a rotoflex (the rubber donut u-joint replacement at the back of the rear axle), but if that's going bad, it could cause harmonics too.

Wheel bearings are timken 37

But I am with John and saying it is the T-case whine.

Oldscout has some oil that helped him maybe he will chime in.
