Got a 98 4x4 150k. While quick acelleration will cause a whiney sound. know that sounls like a ratcheting sound. I found I have to stop and put it 4hi drive 10 feet and switch back to 2hi and goes away, jump on the acellarator and it will do it again. It comes and goes. It low speed it is loud. Once in awhile it will make a bang in the frt end after doing a start and stop routine. Help
