yeah I know there are like a million post on here about the rear diff problems everyone is haveing, but I need some help. My truck is a 2005 dodge ram 1500 has 65000 miles with the bomb shell 9.25 lsd rear end. My problem started with tires sqeeling when making corners from a stop, but now it is making a clicking sound almost like a chatter with a vibration, but not all the time mostly if i have to get on it pretty hard seems to be worse if im turning. if i drive straight it is fine but noise is getting worse also sometimes if I back out and put it in drive I get a vibrating chatter. I changed the fluid and did not see any metal shaving or a clip, but it had been changed before I did it. I bought the truck used from a chevellet dealer with a warranty but they looked at it and said they though i needed new tires and that they put the truck on the lift with it in gear and no noise was comming from the rear end. So what do I do now?

 

Have your tires checked. They could be out of balance. Could be tie rods or u joint as well. Les schwab does inspections for free. Jack up the front and try to wiggle the wheel left and right. If there's play then it's tie rods, up and down play is ball joints. Crawl under the truck and tug on all of the steering components to see if there is major play. Look for torn boots and bushings too. That can start to narrow it down.

 

a ratcheting sound on turns with a LSD is an indicator that there is not enough friction modifier in the differential - did you add a bottle when you changed the fluid???

 

What hammer said.
You need a 4 oz bottle of the mopar friction modifier at least in the diff.
Confirm you either have it or not.
If unsure, add a little at a time say 2 oz until your chatter and grabbing around corners goes.

Oh yeah..... When adding the modifier, drive 4 or 5 figure of eight turns to mix it up with your LSD fluid. Then make tight turns and see if the problem reduces or goes away.
