after installing the ARB Diff Cover and changing the oil my diff makes some noises.
First I filled in 2.5 pts. (1.2 liter) like my manual said.
Today i filled in about 0.5 pints more and the noises are nearly gone.
A friend told me that itīs not good for the diff to use it with too much oil.
Could you tell me whatīs the right oil level at the dipstick?
In the diff there was cheap SAE90 oil, now I have high-quality 75-w140 oil. Could that cause the noises...?
Thanks in advance.
