Thread: Horrible whirring/grinding noise in front end

Hot diff meets cold water can mean it's got some water in there..

ALWAYS (emphasis) pays to check oil condition after a trip full of water crossings.

Well there is a big Note to Self!! Would not have expected water to be able to get into a sealed componenet.


Will get them to check the rear diff, transfer case etc as well.

Hint

When ever crossing water that is deeper than the lowest level of your rims then if possible give the diff etc time to cool down some before entering the water. I tend to stop and make a brew and in that time it's generally enough. If I know a track and there are several crossings I just cruise leisurely between them. Another thing to consider if you are doing regular crossings is to fit breather extensions to all the bits that might suck water in when submerged, especially when hot. Finally as mentioned check condition of fluids post trip.

Hope it's just a little water mate and nothing more damaged

Certainly no component is actually sealed.
They have breathers..

However rapid change of temp - dunking hot into cold - results in pressure changes greater/quicker than the breathers can deal with and the water is drawn passed the seals...

thaks guys. Have not relly done any off roading with it depite having the vehicle for 9 years.


a dumb thumbs mistake.


what is best fluid for the diffs, transfer case?


By the sound of the noises I'd say a bearing has carked it.

Most oil companies have "Refer to dealer" for Front diff and Transfer case fluid - would be proprietary blend..

My searching on multiple manufacturer/oil blending company sites all state refer to dealer.

If they've asked for a specific fluid to be made then yes, proprietary oil... similar to some systems on the D2 which for a long time you had to get ACE fluid from the dealer.
