For as long as I can remember I've had an occasional 'ting' in the driveline somewhere. Noticed when windows open (esp. rear), no radio, and changing direction of travel (F->R,R->F). Still haven't figured it out, but it hasn't hurt anything..........
"It's a big ting" (Cool Runnings 1993)...
In all my vehicles, including 5 trucks, I never had a "ting" in the drive train that was normal.
There will be NO permanent, occasional, or abnormal tinging in my truck.
Now... In my trucks with Detroit Lockers and Lock Rights... I had clunking and banging... but that was normal.
No ting is a good ting.
