Strange intermittent vibration at 65 mph, driveshaft?

Has to be aftermarket then because I have a 2014 and have zerks. That may be your problem, shafts aftermarket and not balanced properly?

 

I’ll raise it at work and have a closer look. I got under the car and just felt around with it in the driveway.

I know when I worked at GM original joints had no grease fittings but replacement GM ones did.

Does the fitting stick out or is it sunk in?

 

From what I recall, it's in there.

When my wife gets home and takes over little man duties I'll take a quick pic if I don't forget....tired lol

 

Mine is also two piece with no zerk.....and I've had it since 2008 so no it's not aftermarket

 

The zerks are painted over and it needs to be scraped off.

 

Pics are for RWD and not the forward shaft.

Fed ones hidden, main shafts are right there easy to see, access.

 

You 2wd or 4x4?

 

2wd

 

@GNX6 are you 2wd or 4x4?

Starting to think maybe 2wd don't have zerks.

 

Talked with my chassis buddy at Toyota...there is no rhyme or reason, some have em some don't

 

So I had an issue similar to this when I bought mine. I have the 20 inch wheels and had 275/55r20 , then switched to 275/60r20 d rated. Mine turned out to be an air pressure issue. I kept 275/60r20 at 55 psi (recommended by tire manufacturer and have zero issues.) If i air down to 45 it vibrates at that speed. When I had the stock tires p rated they always vibrated regardless of air pressure. I came to the conclusion p rated tires were too weak a tire for the weight of our trucks. With the d rated tires it requires more pressure to prevent the tire vibration. Just my experience.

 

I have a 2002, it shakes a lot.... It also makes a clonk sound when I press the pedal, every time.

I was surprised to see the owner manual recommended 29 and 26 PSI in the tires! My Ford is 60 & 80.

Im curious if it's the tires.....

 

My 2020 CM TRD Sport with only 6k miles does the same thing. Very irritating!

 

I have same problem. From 60 to 70mph vibration. Seems Front right passenger side. And yes I do hear a clunk when begining my drive in the morning. And every time after starting my truck & putting it in drive.????

 

No one mentioned alingment,or wheelbalance. I’m driving factory Nitto Grapperlers18”

 

clunk is probably the ABS self check. Normal.

and yes, most often vibrations are usually related to wheel balance if the truck is in good shape and no worn suspension/steering components.

 

Ty for your reply!

 

In case someone else comes looking. Also check your parking brakes. There’s an outrigger inline under the truck about where the driver’s door and rear door meet. Seizes up BAD! Mine was so bad in my 10’ that the cable at the pedal was sticking out like 1.5-2”. Blasted the out of it with PB Blast and grabbed a big hammer to pull the tension back on and remove the slack at the pedal.
Figured it was worth sharing.
