Off road

Fifth gear keeps dropping out in my 2009 Mazda BT-50. It doesn't have to be under load; it will do it cruising at 100km/h. The nylon bush on the gear stick into the selector has been changed, however the problem continues.

My wife's 2014 Holden RG LTZ Colorado has the most annoying squealing noise coming from the front. It's mainly when you turn to the right but I can also hear it when on the highway. I've replaced the front wheel bearings but that actually made it worse somehow? I've been told it could be one of the clips from the ABS sensor may have broken and fallen behind the backing plate and have read just now a lot of people have had transfer case seal issues.
