Vibration when braking?

Got a 3 inch lift and alignment done. Now when I brake, when I hit less than 15mph the truck starts to vibrate and the brake pedal seems to shake. Does not do this when the truck is put into neutral and I brake. Does anyone else have this problem? The shop that I had install the lift basically said that the truck did this before and it is a design flaw and with the lift it is exaggerated now.

 

search ECGS bushing
or could be impacted by driveline angles (which is an open TSB where they will measure / address driveline angle issues)

 

For that TSB, I could take my truck to the dealership to check the driveline angles? My lift wouldn't void it or anything?

Honestly not sure - from what I see reported a lot of it depends on the dealership. Any dealership CAN say your lift caused an issue like this, but others will concede that this was a manufacturing issue that was only exaggerated by your lift. Probably going to be a bit of luck-of-the-draw unfortunately.

That said, if they won't do it, with the right tools and parts you could perform the TSB yourself as I've seen some others do.

 

Can I just go to the dealership and tell them to have the TSB-0237-17 done?

 

I don't think I could trust myself to do it haha! I think I'll try and take it to my dealership I usually go to and if they say no I'll try other dealerships.

 

Everyone else is saying the same thing as well so I think I'll try and go to my dealership tomorrow and see if they'll do the TSB.
