Ok guys im geting a vibration from the front end I think. Happens around 55 on up to 70 mph I can feel it in my floor board. I have recentley replaced my ujoint in my driveshaft new rotors and pads. I changed out the front shaft due to slipyoke had movment. I noticed after I changed front diff fluid my seal around the pinion is leaking not terrible but leaking checked level a while ago. Could this be my cause maybe low fluid

 

Have all the tires checked for roundness and proper balance.

 

Do like Firestorm said and have the tires checked out. You can always rotate the tires and see if the vibration move from the front to the rear. That will tell you if it is the tires or not.

 

Ill try rotating my tires. But what else could it be even if it aint my tires

 

You need to computer balance them and check for roundness as I said. Just moving them around does nothing.

Don't get ahead of yourself. One step at a time, starting with the most likely.

A vibration can be caused by a great many things.

 

Vibrations in the floor board or seat are usually from the rear. Tires followed by the u-joints are the usual causes. You can often "drive through" a tire vibration as you've noticed, less than 55 and more than 70 its fine. Moving them around does not fix the problem, but helps identify what it is without paying a shop money.

 

After all that effort, you will still have to pay a shop money to check and computer balance the tires.

Be prepared to buy some.

 

Just because a tire needs to be rebalanced doesn't mean new tires are needed. Maybe a weight fell off or the lug nuts are loose. Maybe he has lifetime balance and rotation.

 

"Be prepared" in this case means don't be surprised if there is one or more bad tires causing the vibration.

You can't balance a bad tire. As I said earlier, many different things can cause a vibration. A bad tire certainly can and will.

 

My tires are near needing replaced they have around 4/32nds of tread left. Just dont have the funds for new ones I do have 31s like new but I need to lift my jeep first

 

Just wait until you crash into someone due to the worn tires, see how much scratch you have left then.

 

At that age, they could be starting to go out. The vibration is telling you something's wrong.

2/32s is the non-skid tread depth. In my state they are illegal after that. I don't run SUV/pickup truck stuff past 4/32s myself.

Actually, I don't even run my cars past that.

Go real slow when it rains.
