2016 Cascadia, Time to do suspension bushings?

I have a truck that had 350k on the clock, it had one bad vibration when it hit 60, the driver said it was getting worst so we pulled the truck off the road. I drove it and sure enough the vibration was very odd and felt like it was the front axle. There was odd wear to the tires but it was the vibration that was concerning.

I had the front end rebuilt, new springs and shackles, new brakes and tires on the entire truck and it was still bad.

I went so far to have the frame checked and a different axle put on the truck, finally I asked one of the people at Eaton and he sent over someone to check it out.

He took one short drive and said pull the driveshaft, pull the harmonic balancer off and replace them. I got a new balancer from cummins and brand new balanced drive shafts and UJoints.

The truck ran and drove great after that, it had 750k on it as of today.

 

How would one know when to replace the rear leafs? What should I look for?

I’ll get the parts 3 cases of bear or three bottles no matter and enough bbq for 10 people and pay you your time to help me do the whole job.

i bob tail so no trailer.

wanna teach me?

 

You can inspect the bushings with your own eyes.

Unless they're hidden. Shouldn't be too difficult to spot.

As for the drivelines. Lift the rears off the ground and drive the truck. You'll know if the shafts aren't spinning straight with a visual inspection.

 

Like snowwy said. You can see when the rubber bushings worn. A visual gap. My right rear bushing was very evident, compared to the others. The bolt actually wore into the spring a bit. Not bad enough to need a new spring. New ones still fit good. If you have the newer suspension, the wear plates can be an issue. I saw it on Utube. Don’t know much else about it.

 

I think I know which video you are mentioning about west plates. I understand about the bushings and how to spot bad ones, I was wondering what to look for on the leaf it self to determine if it needs to be replaced or not.

 

Mind sharing with us on who did your bushings? And $1200 includes the bushings of labor as well?

 

If I had some room and you wanted to head all the way up into Canuckistan I'd do it.

 

I would have made the cross country trip. But soon as you said Canuckistan, pre covid yes. Post? I’m sorry bud I feel your pain but I don’t want to share in it.
