Hi everyone,
In the continuing saga of my IRS diff clanking noise, with more light and care I discovered that the driveshaft U-joint to adapter bolts ARE too long! Two of the bolts were snugged down but two were standing proud about 1/32 to 1/16". These are the M10x25mm SHCS. I will look for shorter ones, but if they don't exist, I will grind them down as suggested. Factory Five should put out a warning tech note!
Thanks to this forum I have found the solution to my problem. Yea for our team!!
Thankfully,
Jeff
