LSD Diff?

[ns400r]

Hi



How can I tell if I have a LSD diff?



I have searched previous posts, tried the wheels off the ground in N and the other wheel turns in the opposite direction.

Stickers on the diff are unreadable.

What should I look for on the VIN plate.

I have 1999 Ford Freda 4 x 4.

Which oil should I use?

According to the factsheet, you dont have a LSD:

"If you want to check if yours has LSD, switch off engine, gears in neutral. Jack up vehicle so both rear wheels are off the ground. Manually turn one rear wheel. If you have an LSD, the other rear wheel will turn in the same direction. If you have not got an LSD, the other rear wheel will turn in the opposite direction or the propshaft will turn."

In terms of what oil to use:

"Recommended lubricants are:
Standard vehicles-Genuine longlife hypoid gear oil SAE90 (GL–5),
Vehicles with LSD-Genuine slip less gear oil SAE90 (GL–6).”
But if you can only get hold of GL5 (75/90 Synthetic) gear oil, it won’t cause any damage to the LSD”

I changed both front & rear oil recently. I was unable to find any info about the quanties of oil required. For future ref, I found it as follows:

Front: just over 1 litre
Read; just under 2 litres

It was cheaper to buy 5 litres from a motor factor, so I actually used the extra to fill & flush the rear diff. The front oil came out very clean, but the rear was black & thick.

I can't recall the sizes of the sockets required, but the drain & fill plugs are different sizes.
