I just show up here to get entertained

 

I have a noise in the rear diff. It's kind of a low pitch sound, and not raspy or a growl. And it's not a whine like gears make when the mesh is changing from something worn.
Anyone ever jacked the rear up & run it in gear to check what the noise might be ?? Maybe it wont make any noise without a load on it (?) And it's not loud either. Maybe I'm too **** about it.
It doesn't sound like wheel bearings, and eases off a bit when letting up on the gas pedal.
I haven't really checked the pinion for having any looseness or side play etc, and there aren't any lube leaks. I checked lube level a while ago, and it was full.
One thought is carrier bearings. ( that would suck )

Meanwhile, I'm replacing the radio with a Pioneer CD radio. More fun....

 

Did this noise suddenly appear or has it always been there?
Bad bearings make excessive heat, maybe an infra-red temp gun can help diagnose a 'hot spot'. After driving the highway, pumpkin should be around 135 F.

FYI. The 8.25 rear end has a small passageway on passenger side, this allows oil to reach the pinion bearing. If pinion angle is too steep, bearing can starve of oil.

 

'Generally' the Transfer Case is non-problematic. The shift-lever should engage without issue. 4Full-Time powers the front driveshaft through a chain which can be subtlety heard and felt under feet while driving.
Isn't there some grass around?

Something is wrong. Have you checked the chain to see if it is dragging on case? And check the output-shaft bearing and pinion bearing?
I can run 60mph in Full-Time without noise or rattles.

 

You shouldn't hardly notice at all in Full Time.

No bucking, binding or anything.

 

I don't have full time. Lol

 

how difficult is it to fix a head gasket leak? does he mean a rear main seal leak maybe?

I imagine he means the head gasket is blown if it prevents him from driving

 

I see..
In that case, something is wrong. Have you checked the chain to see if it is dragging on case? And check the output-shaft bearing and pinion bearing?
I can run 60mph in Part-Time on the beach without noise or rattles from the transfer case.

 

My rear wiper is not working. Fuse is good. Cant see any problems with the wiring.

I have the wiper motor out.
There are four wires from the motor to the clip. Black, Brown, Grey and White. They lead to a relay attached to the motor.

How do I test to see if the relay is bad or the motor or both.

Activate the switch. If you get power to the wires for the motor the relay should be fine. Chalk up a new motor

 

Thanks for the tip.

Anyone know if a woodruff key off the end of a 258 crank will drop into the slot on the end of a 242 crank? Lost my key either during disassembly or while at the machine shop.

 

Well, since I have a 4.0 harmonic balancer on a 258 crankshaft in my stroker, I'd have to say probably.

 

Thats a negative
