hey guys yesterday after i got off the highway and sat a stop light for a few minutes the light turned green and as soon as i hit the gas i heard a thump noice below my feet. just one thump...its not a rock or anything. sounded like somthing had a bind in it and came loose.. it drives fine and it only happened once. curious if its just the fact that i need to grease the drives shafts..

 

Might be a u joint, time to grease that drive shaft up. Just my 2 cents, That is my guess.

 

yeah i may have missed a nipple or two last time haha... i am going to do alot to it this weekend. its right at 80k miles. gotta change the oil, lube drive shafts, replaice fuel filter and plugs, seafoam, and change the gear oil in the front, rear and t-case...
