Chuck said the same thing ^^^ nuts need torquing.But I will lube the axles etc.. to. any specific LUBE? to do this?
I'm also having the same problem..I'd also like to know does it matter what kind of lube/grease?
Lube the axles? Don't think there's anything on there to lube.
The u-joints are sealed, and also cheap. Put new ones on.
The slip splines on the shafts are sealed if the boots are intact. Nothing to lube there unless you are tearing them apart.
If you have suspension mount points squeaking you can use a variety of lubricants, from WD40 to silicone grease etc. As long as it does not attack the rubber bushing it really doesn't matter. And most common lubricants will not attack the rubber.
You will however, have a limited result just spraying something on the outside of the suspension bushings. It will wear away over time requiring re-application every now and them. Way easier tho than disassembling everything to get the lube on the insides of the pivots where it belongs. Just keep whatever you use off the brakes or rotating components where it could be slung on to the brakes.
You should do a complete re-torque of your diff housing and suspension if that has not been mentioned. I had no noise and all mine was tight, but you should check it.
