Subject: [Healeys] SAE 140 Use In Differential To Reduce Noise?

Hello All,

The differential on my 1966 BJ8 starts to whine once I have driven for
several miles, and everything has warmed up to normal operating temperature=
.
It only occurs during accelerator pedal movement down (under load). The
whining diminishes during coasting or deceleration.

The differential is filled with Penrite 80W 90 mineral gear oil. (Recently
changed).

I am considering replacing my differential gear oil with Penrite SAE 140
mineral gear oil. (Note no 'W' prefix; it is straight SAE 140). This produc=
t
claims it will reduce differential noise in older vehicles. I wonder if it
is suitable for our Healeys?

I seem to recall reading on the List that our rear wheel bearings are splas=
h
lubricated by differential oil, but cannot find any reference to that in my
workshop manual. Is that correct? I'm concerned that if that is the case,
will the SAE 140 be too viscous to splash lubricate the rear wheel bearings
effectively?

Would I be better of using a gear oil additive like Nulon G70 instead?

Any shared thoughts or suggestions would be greatly appreciated.

Thank you.

Regards, Graham Wilkie.
BJ8 Moruya NSW Australia.

replacing my differential gear oil with Penrite SAE 140<br>mineral gear =
oil. (Note no 'W' prefix; it is straight SAE 140). This =
product<br>claims it will reduce differential noise in older vehicles. I =
wonder if it<br>is suitable for our Healeys?<br><br>I seem to recall =
reading on the List that our rear wheel bearings are =
splash<br>lubricated by differential oil, but cannot find any reference =
