Spring Clamps Reduce Rear Vibration

[Brakin7]

My truck doesn't let you select 4wd without prompting you to go into neutral on the screen. Yes, I meant to post here because of my shake at ~40-50mph. Put it in 4lo to crawl out of a mudhole in the driveway. Thanks for the info!

Yeah 4hi would be sufficient honestly for future use, most people will never need 4low in their life honestly

[Brakin7]

Sorry, id understood that 4lo is for crawling and slow action, hi is for hiway use. Maybe I read wrong...

From the owners manual:

 

(Four-Wheel Drive Low):

This setting also engages the front axle and delivers extra torque. Choose if driving off-road in deep sand, deep mud, or deep snow, and while climbing or descending steep hills. When engaged, keep vehicle speed below 72 km/h (45 mph).

 

note the "and". Even in these situations you probably won't need it.

 

 

Edit: Use Auto for Highway, 4Hi for off-road / extreme conditions, 4Lo when you need more torque in 4Hi conditions (rarely if ever).

 

 

Your issue is probably a little separate but would be nice to see your vibration now in a video; If its a similar vibration we can probably narrow the shake to the front end like I've suspected for a while now.

If he has the vibration after the CV axle replacement that would be my first guess that they do not meet spec

[Brakin7]

Truck drove fine even with new CV axle, but loaded. Unloaded i can feel it bounce my gut at those speeds. Doesnt come thru steering column. Just in my back and butt.

Before you had your driveshaft balanced and trued, did you ever put your truck in neutral to see if the vibrations/shakes quit? On my previous truck, 2000 Silverado z71, the driveshaft was so out of balance and u joints were so worn, whenever I put it in neutral going down the road, the vibrations immediately stopped.

Get your driveshaft checked by a specialist. I have no more 75+ mph vibs since I had it rebalanced

Please elaborate on your symptoms, truck specs and remedy. Thx

Mine has the shakes between 70mph-80mph. Going back to dealership on Friday.

Update:

The shaking seems to have gone away for a little while. I have not felt it in a few days...... wierd

Where do you feel the shakes most, seat, steering wheel, or console? I have a 17 that shakes occasionally too.

 

Sorry if you've already mentioned it elsewhere.

Exactly where I feel it. Stinks this is still going on with the 17s.

 

Thanks for the response.

[Bikemobile]

Yup, I felt it with stock tires and with duratracs. Dealer says its the duratracs. Not sure what to do.......
