tyre noise and correct tyre pressure for high temp
I have 2008 Dodge Durango milaege is about 127000km , with standard tyres, I use it mainly on regualr tarred roads, for school run etc, though occasionaly go offroading in the desert, the avearge temp here are about 45 degrees celsius in summer can get to 50+ so Im not sure of what tyre pressures they should be at, currently at 33psi as per label in drivers door I would like to know what could be causing the annoying noise when I'm driving most notable between 80km to 110km per hour. its like hum/whine and its not my bearings have had them checked and not my kids in the back either
First check the oil in the difs and the t-case, ad if to low and if the oil in the difs is milky like it has water in it and needs to be changed. If this does not fix it check the drive shafts for a little play in the joints if there is play they need to be changed. If not the shafts it could be in the diffs and then you need have them checked out maybe time for rebuild. I always start on the easyest and cheapest thing first so do this in this order :o)
