Hello All,
I'm relatively new to this although I have been looking a bit. I do not want to discount all previous posts on this subject.
However....
I have had some (I thought serious) problems with my GU Auto Hubs. You know, seeming to come on, making ratcheting sounds, trying to disengage them whilst driving etc? Well last time I took the car to get serviced, I asked the mechanics to take one final look at the hubs before I was going to replace them - and this is what he did . . .
He took one look at the oil in the transfer case and saw it was the wrong type. It was too thick. He replaced the oil with thinner oil - something like you would put in an automatic gear box.
And he explained to me that the thicker oil picks up the end of the transfer shaft to the front diff even though it is not engaged and it puts a slight spin on this shaft. This in turn rotates the front axles and the Auto Hubs (because they work) also try to get going.
I hope this helps some of you with similar problems with the Auto Hubs.
Since this has been done on my car we have travelled 2000 km without the hubs once trying to engage without being asked to. It feels like a new car even though it has just done over 200,000 km (this happened last night). I'm soooo Happy
My car is a 2004 GU 4.2TD intercooled with gas injection. We are about to go from Perth to Broome.
Happy travelling you all.
Jack
