Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
With this rumble if you turn side to side when the noise occurs carefully does the noise change pitch at all or go away when this is done or possibly get any louder?
Let me know so we can continue,thanks Pete.
I apologize for the delay.
The first thing that needs done here is to have the fault codes read out/checked with a scan tool that will plug in and communicate with all computers in your vehicle here.The fault codes set once this has been done will need to be diagnosed to locate and repair this issue here.I would start with having this done first to see if the fault is located this way.
If the rumble does not change noise turning side to side and only occurs with the vehicle moving or slowing down this indicates a fault with one of the bearings in the rear differential most likely or gear wear in the differential needing replaced.I have also seen issues in the transfer case as well before needing repaired or replaced.
This will have to be inspected further to locate the cause for this issue here and then from there it can be repaired to correct this.This may require having a shop or repair facility take apart the differential or transfer case to inspect and repair the fault here.
