82 F150 speedometer gear
The problem started about 2 months ago when the speedometer stoped working. We ended up finding out the gear had broke so I put a new one in and that on gave out after 5 days the third one had lasted for about 2 weeks but now that one died. The gear gose in to the transfer case and I'm at a loss on what to do now becouse it take a week to get one ordered in only to have it crushed. Any thoughts on what would couse this.
