LX 5.0

I am determined to maintain my car 100% How often should I change my differential fluid? I have replaced my tank, fuel pump and filter because the car was stored for 10 years. The first new pump was loud making a high pitch noise. The mechanic who did the work wasn't familiar with the car but I don't have to many options over here in Denmark. We concluded it was a defalt. The second pump makes a consistant quiet noise. Is that the correct amound of noise?

And you got that info from where? Guess you've never seen inside a rear end.


The fluid, any fluid for that matter breaks down over time. Not to mention the mechanical parts they lubricate wear and contaminate the fluids They should be changed every 30K. Preventive maintenance is what it's all about!!
