Hi everyone! thanks for all the help before concerning my hubs, new issue i just encountered tonight. I went to start up my 2001 4x4 auto blazer and when i put it in reverse to back out of my parking stall, i experienced a loud grinding noise coming from the frontish area of the vehicle. Upon hearing this i put it back into drive and drove forward a little and proceeded to put it in reverse again, same grinding and almost crunching noise. I recently replaced the driver side hub assembly (dont know if this is relevant or not).
Does anyone have any possible insight as to what the noise might be? cv? brakes? tranny?
I am willing to look at anything and everything to try to diagnose the problem. Thank you in advance!!

 

I believe a grinding/crunching in reverse is the Sun Shell in the transmission breaking down. Unless something is really wrong with the front hub I'm guess it's strictly coincidental. You should either plan on rebuilding/replacing the transmission shortly or else have it checked in case I am wrong.

 

i had a grinding noise when back-up, that got worse and grinded all the time at low speeds. i asked my wife to back-up slowly while i walked on the side of the truck to see where it was commign from.

it was simply rust build-up on my rear rotor grinding on the galipers.
it took 5mins and it was free !

might be this, take a look thru your wheels and look to see if your rotors are rusted.

 

bah, so new update, when i drive in speeds over 50kph now i hear clunking and clinking going on in the front end, scares the bejesus outta me. there seems to be no rust buildup or anything like that on the rotors. i will however also take a look at the recently installed hub to make sure everything is ok too.

i just pray that i havent done excessive damage to my front axle for whatever reason...dreading the bills so bad.

 

Yeah it's probably rust on your roders. That's what mine was

 

what would explain the clunking and clinking in the front end though when im driving forwards

 

Is it when you turn?
