Already at 100k

What do you guys do maintenance wise when your vehicle hits 100k?


A little bit of background..
She's going to be in the shop getting looked at for a loud squeak/chirping noise coming from the rear u-joint/diff. I'm also having the mechanic look at my whole drive train. There seems to be a lot of play in the drive shaft (refer to my thread about the clunking after coasting).

I had her in the air on jack stands trying to see where the noise was coming from, and noticed that the front tires were not spinning. At first both rear tires would spin then the drivers side would stop. locked the diffs and the same thing happened.. I hope that this is normal..

Also, I was just gonna replace the spark plugs and was wondering what else you guys all recommend doing. lol I'm pretty sure everything is factory.. besides the trans fluid that was replaced the last time she was in the shop and the K&N air filter.


Thanks Much!
