I found a solution to the annoying creaking sound from the bell housing\slave\clutch area. Some say the noise is just the slave cylinder but in my case, it was not, I've tried 3 of them. Some have had transmissions swapped, clutch disc, pressure plate and throw out bearing all replaced, and still get the same noise. It's caused by lack of grease on a pivot and pilot shaft.
Here it is. It sucks and it pisses me off.
YouTuber Jeff found a similar solution that led to the idea for the procedure that worked for me. In his '12+, there is a small panel cover between the engine and bell housing area that allowed him to spray grease backwards towards the fork, pivot and throw out bearing. Thanks for the ideas Jeff! The fix for my '11 was stupid simple. I drilled a hole to create a grease access port to the fork pivot ball area. I sprayed some Lithium grease on that pivot ball "area" inside. I've always suspected the creak was originating from that pivot and the throw out bearing pilot shaft. I've been running for a 8 months now, over 8000 miles plus 3 wheeling trips... nothing but silence from the clutch every day.
Can of Lithium Grease with the spray straw
Cordless drill and some bits
Socket wrench, short extension and 13mm socket to remove\install the slave
A short allen head screw and some RTV
Some high temp red grease
Optional: New Slave, MOPAR Dot 3 Brake Fluid and a bleeder tube if replacing the slave
1) Remove the slave, bend the spray straw about 90 degrees and spray the throw out bearing\pilot shaft "area". Again, just do a few short blasts until you think you got the area covered. You'll be sending grease towards the pilot shaft, fork pivot ball and throw out bearing.
2) With the slave out, some say to grease the inside pivot of the slave itself, the tip pops off. Others say to grease the outer pivot of the slave where it contacts the fork. To each his own. I don't think it matters but I greased both with some red high temp grease.
3) Reinstall slave.
4) Test drive for a while and see if it helped. If you still have the creaking noise, proceed to step 5.
5) Drill the friggin hole in your bell housing. 1/4" or so should be more than enough. It's soft aluminum, drill a pilot and then a final, it takes just seconds.
6) Bend the spray straw as needed and spray some Lithium grease on the pivot ball "area". A few short blasts will do it, not towards the clutch disk.
7) Find a short allen head bolt about the same diameter as the hole you drilled, and use the bolt and some gasket RTV to plug it up. Let it cure overnight. Should be easy to remove for regular lube maintenance.
I also recommend Mopar DOT 3 fluid. I had better results vs aftermarket Dot 3 or 4, for what it's worth, just in case you actually have some noise generated by your slave.
I hope this helps.
