SuperD,

Here's something you may want to try. LINK Rear drive shaft slip joint lube.

 

My brothers 08 does the same thing. Only when towing and only when starting off from a stop. Wonder if this is whats going on? It has less than 30k.

Brad, under what conditions were you having the vibration?

 

1800 to 2200rpm when towing very fast vibration.I am picking up some lumber today,and will know for sure if it was the carrier bearing.

The vibration has gone away,but I haven't towed with it yet.I'll let you know tonight what happens.

 

Cool. Thanks Brad.

 

Great write-up, mine has a slight vib at highway speeds, now i know how to replace the carrier bearing. Thanks Brad!

 

If yours is only doing it when starting off or from a near standstill, you probably need to grease the slip yoke on the driveshaft like PaysonPSD said...

No more vibration when towing! The carrier bearing fixed the prob for me.

Now to grease the slip yoke.Should of done that when it was apart.

 

Jees Brad, you didn't do that, you had it all apart

 

Thanks for the update Brad. My Bro is towing a camper down to the Outer Banks tomorrow and we'll see how it does. If it still gives him problems we'll adress it when he gets back.

 

i have a question i just put a new carrier bearing in my dads truck today and i put it together just like in the pictures but the metal clamp has a arrow that suppose to face forward but it faces to the rear axle???? it came out of the box with a metal tap holding the two together can i just cut it off and flip the bracket or did i put it in backwards??

 

See how the rubber is facing in this pic.Thats how my came off and I put the new one on the same way.Yes I had the metal bracket off,so you could flip it if you have to.

 

Agreed, nice write up. Reps headed your way.
Thanks for taking the time to put that out there!

 

I replaced my carrier bearing when I did my trans rebuild not too long ago. I had a torch, but used a different method that those who don't have one might try. I did, however, use a 4'' angle grinder. I removed the hanger bracket and cut the rubber like Brad said. I them use a hammer to crack the outer race and remove the ball bearings and cage. I cut a groove in the inner race with the angle grinder and then split the race with a hammer and large chisel. Be sure and wear eye proection with this method. There may be flying parts!

 

do you see the bracket in beanheads pic guys? the bracket in the box i got from the dealer does not look like the stock piece, its just a horseshoe and doesnt have the extra lip in the pic facing up. i should just takle a pic of it installed and let yous see what im talking about

 

Yes,take a pic and we'll go from there.

Did you get your carrier bearing from a dealer or parts store?

Guys Roland has a good way to remove the bearing or if you can get a three arm puller that would work also.I was a field mechanic for ten years,using the heat wrench is a habbit of mine.
