I have a 2007 my08 triton with uprated rear leafs (for boat hauling i guess). its second hand and has just clicked over 220k.
Lately an issue has started and is really perplexing. sometimes when driving (daily driver), as i go to slow down at the lights a lght grinding noise starts and then once the car has stopped a clunk can be felt and heard from the front end. then the light 4wd light starts flashing despite no change to 4wd selector. when start to move off agaiin the light continues to flash for a while but then goes away. Sometmes it hapens twice a day and others it doesnt happen at all. there is a definate engagement of something somewhere up front and it definately sounds like a constant non-meshing of something.
yes ive searched as many forums as i can with no luck, its not tailshaft related i dont think.
to be honest it sounds like something is comng lose and waiting for a slow speed to enable it to engage. If i put it into 4h the light stays solid and there is no noise.
