how often should you change your rear end fluids and oil?

 

about every 30,000 miles says the Haynes manual, ps if your checking the fluid level don't stick your pinky finger past you knuckle, I did and got my finger stuck and had to force it out and ended up with a nastly cut from the threads, but your prolly not as dumb as me!

 

I used Redline-Changed every 50,000 miles. More often sure wouldn't hurt.

 

Just stick to the every 30K miles scenario for tuneups & 3K miles for oil changes.

Now if you don't drive much, that's where I get confused. Is it "whichever comes first" - 3 years or 30K miles for tuneups? ... and 3 months or 3K miles for oil changes?

 

yep thats what haynes manual says.

 

Just sniff it (you'll know if it smells burnt - if it does, change it) and stick your finger in. If there's crap suspended in the fluid, change it.

That would be my 2-step plan.
