drive train vibration

I am experiencing subtle vibration in drive train when I accelerate hard from slow speed. Anyone experience similar or have thoughts?

many thanks!!

 

Is your truck stock or have you added mods?

 

Very common on these trucks check out the link

Thanks you guys!

Truck is stock, 1500 miles so far.

The background information was very helpful and appropriate. Before I get my creeper, I think I may give the OEM an opportunity to address the issue.
Wish me luck...

 

I dub this, the official 10 stages of Stock Driveline Vibration


good luck (my advice, jump to step 10)

1. first your going to go in and the dealership will tell you its normal



2. then your going go back and say its not, they will look at it.. test drive it and tell you they cant feel the vibration



3. you will drive for several more days as the vibration gnaws at the core of your very soul.



4. you will go back, again and now their "master tech" will say, "o yeah its a problem but, we call it a characteristic of the vehicle".. again you will leave



5. a couple days and 4000k shudders later you will escalate it to Toyota customer service in a rage-frustration fit....



6. then you will go back toyota and the dealership will "drop your axel and put you in 4hi" to confirm its the rear driveshaft, then they will promptly replace your rear driveshaft



7. you will leave happy...



thinking problem gone
but its not.....



9. you will go back and toyota will send out a 50 man team of "engineers" out that will do nothing more then spend days with your truck scratching their head....



10. you will inevitably get frustrated and give up after spending the equivalent of 10 days of your time and skipping out early on work several times to "drop the truck off", learning to deal with the vibration/shudder.



OR (Secret step 11) Design you own Custom solid 1 piece drive shaft with a CV joint (sorry prerunners) from a 1999 4runner and call it a day.

 

I'm on #6, and they're saying they won't replace the driveshaft - they want me to drive it for 5000 miles... then they'll probably tell me it's the tires. Spoke to Toyota yesterday - they'll either fix it now or buy it back from me. More news in the other thread hopefully next week.

Too bad too, I like this truck aside from the incessant faulty drive shaft prob.

If I end up getting refunded by Toyota, this will be my first and last. And, AEV will get my money (and a little more money) http://www.aev-conversions.com/vehicles/aev-brute-double-cab

 

i honestly think the rubber that surrounds the carrier bearing is way too soft for this application. it flexes too much even when new

 

I put a clamp on both leaf springs to help with axle wrap and now I get a vibration at 25-30 mph. It goes away above and below that though. I'm keeping them because they certainly help with axle wrap on hard acceleration and braking.

 

Did you just clamp the front of both leaf packs? That will change your pinion angle cause this. Why not clamp front and rear and see what hapens?
