I m sure most of you aware that 04/05 F150 has some issue with slip yoke (shudder on take off only) and there is a TSB for it.

I had a little issue with my truck FX4 04 shudder on only take off straight.

My rearend limit slip already has replaced the clutch and its all good!

I decieded try it myself, i removed driveshaft, used regular Valvoline grease and applied it and it works as smooth for approx 4 weeks then it start slowly came back....

So i ordered Teflon grease thru Ford dealer part dept that they use it for TSB and i applied it and its sad to report, it only last 17 days !

Soo do you have any suggest BEST grease that doesnt dissolve quick and best last longer ??

I havent try mobil one grease...

ANy feedback?

Thanks!

I've had good luck using the Ford Teflon grease. I always clean the inside of the slip-yoke first with brake clean before applying the grease to the slip-yoke splines.

 

damn..how often do you apply it ? is it once or ?

.i also used telfon grease but it doesnt help at all!

I even used brake cleaner too

How much grease did you fill it in ?

Thanks!

i have a 2000 f-150 sport v-g 2wd, and at 60k i started to feel something go wrong in the rear end and it ended up to be the u-joints going south. we replaced them with greaseable one and i havent had a problem with them since. this might help u out.

 

Yoman,

I went through this with my 2002 F250 and that Ford crap never worked for more than two-weeks. I finally used a "marine" grade bearing grease and never had anymore problems. If that stuff can take the saltwater it can surely lubricate a truck slip-joint

Also don't go crazy with the grease or it will hydrolock and not move properly....a THIN coating is all you need!

 

I have asked this before with no answer. If it is a 2WD with center carrier bearing which slip-joint are you talking about, the one on the Transmission or the one at the center carrier?
