Hi,
When I first up the blazer I have to press the auto button and allow the light to stop flashing (if it doesnt I will move into D or R then it clunks in) then I have to press the 2W Hi button.. it then makes noises then it kinda clicks in and the servcie 4x4 light comes up.. it is then ok to drive, if not the steering is very stiff and when turning there is loads of noise from the front end and juddering.. Any ideas what might be up???

Thx
