Question about 2002 Cadillac Escalade Ext
We have a 99 cadillac escalade when we get up to 60 mph it vibrates in the stearing and makes a strange poping noise when you turn. We have replaced the transmition filter, the fuel fiter, and lower ball joints we are out of ideas and no one seems to know
Hi I am Vortash .. I have to say first that this is not a car I have ever worked on , but it's a car so the fundementals will still be the same . Steering shudder usually occours due to 4 things Road wheels or suspension or steering itself ( this includes the ball joints that you say you have replaced )
1/ when you have new tyres fitted it is usually par for the course that they are balanced , this is the wheel is spun mechanicaly and a machine measures the axis wobble or TRUE .. a metal weight is placed at a point indicated by the machine to equalise the weight and give a true spin.... These weights sometimes come off causing the wheel to shake .
The wheels are buckled pot holes cause severe camage if hit at speed also knocking the tracking out causing tyre exstensive tyre wear .
2/ The suspension uhits .. if they become damaged they themselves wobble transfering movement to the steering
3/ steering the track rod ends wear and become loose allowing the front wheels to again wobble and run out of true .
4/ wheel bearings worn severly
The popping you hear I suspect is the sound of the tyres being dragged one way or the other traping air and poping it out , but I would have thought to do this the tyre pressure would have to be extreemly low .. you should have a miniumum of 24psi in the front and 28psi in the rear which is increased at the by 10% if towing .
I hope this is of some help Regards Vortash
