She shudders when I accelerate away from a stop

Before I climb underneath...
2015 DC 4x4 4.0
135k miles
She shudders when I accelerate away from a stop.
U joint? Which one?
Thanks, experts!!

 

Have the ujoints been greased regularly, ever? With that mileage even with decent service you may need all 3 rear joints and a center carrier bearing. More information is needed as to whether you have added a lift, etc. that could affect the drive line angle and whether the drive shafts have been inspected for damage.

 

If it is a U Joint they all should be replaced.
You need to go under and check.

 

Are you on a lift?
More than one person has been down this road with a lift.

 

No lift......stock truck right down to the wheels and tires

 

Could be the drive shaft slip yolk at the transmission.

Needs to be cleaned and lubed with teflon grease.

The one at the differential was frozen on mine. Replaced them all with greasers as well as the carrier bearing.

 

there is no slip yolk on 4x4

 

My bet is worn clutches, torque converter lockup. Manual or auto?

 

manual or auto ???

 

Wanna bet you lunch money on that?

 

Ok little things. He said slip yolk at the transmission..

 

When did you last grease the u-joints? Might be all that’s needed and your hesitation to craw under tells me it’s time. I do it every oil change or tire rotation

 

You're right. I stand corrected.

 

No hesitation. I work on everything from boats to old Pontiacs to motorcycles. Posted to see if there was a common item that wears first. Thanks for your reply!!!

 

Auto
Didn't know that a stick was available in 2015 a DC 4x4 4.0 SB

 

I shudder sometimes as well. '14 manual trd sport 4x4 lifted by the previous owner. Purchased with 96k on mar-3 2020 and truck has 97.5k now.

Things I've done:

New diff oil front and rear
New transfer case oil
New tranny fluid
Greased all u-joints (there was grease in all of them)
New brake pads and rotors in the front.

Sometimes I hear a clunk if I release the clutch too fast after shifting into 5th going ~50mph. Shudders in 1st sometimes too and most of the time smooth as butter.

Might be the clutch on mine.....

 

All u-jounts, remove center bearing, install one piece driveshaft. Get the dealership to do the recall first to get new u-jounts and driveshaft free, then fix it for real.

 

What recall are you referring to? I am the original owner and have not seen anything from Toyota??
