Another Vibration Thread

It’s a relatively simple job with the right tools. Most of us do it ourselves but if you post on your local threads I’m sure there’s ton of people willing to help.

 

Definitely recommend doing it while you install the lift. You want to take the whole spindle off. I didn't, and we were hitting our fingers with the hammer we were using because there was no room and it was a mess. You can totally do it yourself though. You'll just need bearing drivers (the ones from harbor freight will do) or if you get it through ecgs you can get the driver with it, but the ones from harbor freight come as a kit, so it depends on what you want laying around. By removing the spindle you'll be able to see what you're doing much better too. It actually would have been one of the easier things we have done to the truck. Just would have to be careful with the brake lines is all.

@boogie3478 actually has a really good video on it. We watched it after



My only recommendation is when you're taking the CV shaft out, they did it kinda weird in the video, we just put a pry bar between the diff and the CV shaft. Came right out.

 

Also, if you use the ECGS tool, you will have to grind it down enough to get it to fit into the groove behind the needle bearing. Rule of thumb, grind 12 times measure none lol.
Once mine was close enough, a prybar and a hammer get it the last bit of the way in, then I threaded the rod pretty deep through the t-nut and that left enough room for a deepwell to fit over the bolt and have the plate sitting flush on the diff. Then hit it with the impact till it comes out. You might have to back off the plate to make sure it clears all the way out.
Careful not to damage the black seal. I bought one with the bushing just in case.
Make sure if you busted the needle bearing to reach in with a magnet and clean out any chips or shavings. Recommend to flush the oil also after.

So far, no more vibes and no leaks. So I must've done something right!
Once you get everything back together, spray everything that got diff oil on it down with brake cleaner then let it dry, that way you'll be able to see if you have any leaks.
Make sure to take it in for an alignment after since you're also putting in a lift if you didn't already plan to.

 

*cough* firestone lifetime alignment *cough*

 

Great info fellas. I'm pretty mechanically inclined. After watching the video, it doesn't look too tough. One question, has anyone ever got the DEALER to do the ECGS fix under warranty??

 

• Wheel vibration and/or wobble.
This is generally associated with a damaged or worn tire, wheel or suspension component or severe chassis misalignment. When related to the hub or bearing, this normally indicates the loss of clamp or a bearing with extreme mechanical damage. It also can occur when lug nuts are not properly torqued.

• Shudder, shimmy or vibration at a constant speed.

This is normally associated with worn or damaged suspension components or tires that are out-of-balance or out-of-round. It is not normally indicative of hub or bearing damage.

Specs on wheels and tires?
Alignment numbers?

The 27 mph and below...
Do you have consistent braking habits?
Can you induce it at a higher speed by braking more aggressively?
