[QUOTE="ogdobber, post: 1162261, member: 22629"] I searched and i couldn't find a thread on this so i created this. TLDR get a new slip yoke[emoji13]. The symtoms can vary from just a squeak when accelerating (or stopping) to a very distinct clunk. Video showing clunk below [YT]_7KhF6dmuP0[/YT] This is the result of a lack of lubrication causing excessive tolerances on the slip yoke splines The only solution is to replace the yoke. I recommend adding a zerk fitting and grease every oil change. If you don't do a grease zerk then you will have to remove the driveshaft to grease (which is a pain) and it needs to be lubricated regularly. Just greasing the "clunk" is a temp fix and will come back (sooner than later) Additional note. When lubing via the zerk, just a couple pumps of the gun. If you pack it full, most will find its way into the transfer case 5000 miles ago i packed the yoke with lucas sticky red and after a hard offroad session in baja the "squeak" was back. Taking off the driveshaft shows it is nearly dry. So greasing is just a temp fix, if you have a clunk/squeak replace the yoke [ATTACH=full]271091[/ATTACH] I installed a 6mm x1 zerk. The drill needed is a 13/64 [ATTACH=full]271092[/ATTACH][ATTACH=full]271093[/ATTACH] New yoke [ATTACH=full]271094[/ATTACH] High quality zerk [ATTACH=full]271095[/ATTACH] ford teflon XG-8 PTFE grease is the ONLY grease to use Here is the part number for a tub that can be packed into a grease gun (haven't been able to find a tube as of yet) [ATTACH=full]271096[/ATTACH] This is the part number for a 11-13 screw slip yoke. Not sure if will fit a 10 or 14, it can be found at tasca. They will ask for vin to make sure it fits. #BL3Z-4841-F Grease D2AZ19590A is superseded by xg8a can be found on Amazon [URL]https://www.amazon.com/dp/B00BNVK5SM/?tag=fordraptorforum-20[/URL] Sent from my iPhone using Tapatalk Pro [/QUOTE]
