I got my jeep Cherokee 98 two days ago and it's leaking oil and it squeals loudly when driven over about 80kph. Does that mean that my diff is going?
I've had to take it back to the car yard.
Also what does it mean when the sensor on the screen says radiator sensor bad?
Bloody cars hahaha

 

I meant 2008 model

 

do you know where the noise is coming from exactly? try putting it in park and reving the engine and see if the noise happens...

 

where is it leaking from? you probably just need to replace a gasket

 

ok, don't make 2 of the same threads!!! go buy your self a gasket! now there should be a plug that requires a 3 eights ratchet to open... unscrew that if you can't see fluid it means its too low... I,d assume this is where the trouble is coming from seeing as its leaking so go buy some gear oil and a gasket replace it and it should be good.. while your in there keep an eye out for damage and report back if you see anything fishy!
