On top of the diff is a small breather cap. Check that isn't blocked after the trip or that will cause diff oil to leak out when hot. The other thing to check is that no water has got in the diff via the breather cap- as that may have same effect.

Find a straight road, stick the car in 4WD for a bit to churn it up (don't use 4WD on bends!). Then drain some off to check for water content. If emulsifed drain fully and re-fill with fresh Hypoid Gear Oil.

Do 2nd Gens have limited slip diffs like 3rd Gens?

If so, make sure the hypoid gear oil has the LSD additive.

Castrol do a Hypoid LS90 gear oil & Comma do a semi-synthetic 80W/90 for LSD gear oil which is the one that I used, as it was easier to find than the Castrol.

If you go to a Toyota dealer they can get the Castrol but only in 25 litre drums. Comma supply it in 5 & I think 1 litre bottles & is available from most motor factors.

Comma I think are part of the Texaco group, so the oil is good quality.

There's sometimes and LSD option on UK 4Runners. Never heard of one on an import Surf.
