binding shafts and new springs
I've read lots about binding propshafts; I'm still not sure...
I've replaced the standard 235/8R16's by 265/75's (same roling diameter) and swapped out my standard 110 front springs for the LR heavy duty items (which are 130 front springs) to level up the saggy front end due to winch and barwork.
The vehicle sits level by eye. I wasn't intending to lift it at all. Mission accomplished? but then...
Very occasionally, at about 80km/h when going downhill, I do get a kind of a metallic vibration from the front. Can't feel it, just a noise, and it might happen once or twice every hour of highway driving. As others have noted, if I coast downhill and then let out the clutch I can make it happen sometimes, but it's very brief and only occasionally.
Is this the dreaded "binding" and what's it doing to my driveline? Is it worth the cost of the double cardan shaft when it's prtty minor? Or is it more serious than that??
