Thunk Noise - Opinions Please

DJWUJZ- A quick follow up. FSM calls for an SST to remove the top AHC shock bearing. Did you have to do this and did you find a non-factory tool that would work? Thanks in advance.

No, sorry, my truck is Non-AHC

What is the grease of choice for this slip yoke cycling operation..? Different grease for hotter or colder climates? Particular brands that are better or worse?

Any Moly Lube would work great, however many folks like to keep it simple and use the same stuff we throw in our u-joints, etc.

Valvoline SynPower with moly works for me, use it in the uni joints and slip yoke every 5k miles. Modern synthetic lubes have pretty broad temperature operating ranges so in this case one grease should fit most. Check out Valvoline's website for their applicability recommendations if you think you might be in a temperature outlier region. You will be ok with just about any name brand, moly fortified, correct NLGI weight auto grease.

FSM says NGLI #2; I use Mobile 1.

Sounds kinda simplistic, but my spare tire was loose and made a similiar noise on accel. Folks on this forum have taught me to start with the easy stuff. Without them, I never would have thought of the spare...

For what it's worth, I think you're supposed to use grease with Moly on the slip joints and grease without Moly on the spiders. I know that using the Moly grease on my slip joints worked better than non-moly grease. I don't know if moly grease will damage to spiders (I have a cheapo grease gun (from amazon) loaded with each--even though I've forgotten which is which).

Note that this is the most complex DIY I am capable of (and it's really not complex at all, my kids could do it). Sometimes I pay the dealer extra to do it, just for the convenience.

Bought a grease gun and grease. Clunk is gone. Thanks for the tips. First lil thing done on the LC

I greased up mine with 8 pumps the first time. It still clunked, I got on here and did some reading, went back under there and gave it about 30 pumps front and rear. At first it still clunked, but after driving it over the course of a few days, the clunk is gone. I used whatever old grease was in my grease gun, not sure what it was.

surprised this hasn't been mentioned yet, but there is much info in the 13 pages of clunk/thunk discussion here:
