Isuzu Rodeo makes grinding sounds when turning right or left and it seems to be coming from the rear of the vehicle what could be the problem?

I have a 93 rodeo and my truck was doing the same thing until the rear wheel finally froze up on me. it seems the drum shoes in the rear will snap and grind the inside of the rotor. not saying thats it, but thats what happened to mi

Rubbing

if you know it is comming from the rear.then it is 1 of 3 things. the tires are rubbing against the fenderwell,the rear wheel bearings are going out,or the third member in the rear axel is broken(i mean missing some teeth)

fluid

I recently bought a '99 Rodeo LSE and my vehicle was doing the very same thing when I made tight turns. I have also heard of this happening on other cars.

The source of your problem is the rear differential. This is what allows one wheel to spin a greater or lesser number of times than its opposite counterpart. In my Rodeo (4wd V6 LSE) i have a limited slip differential. You can tell if you do too by checking the sticker under your hood on the driver's side. If it says G-80 or something like that (I can't quite remember) then you too have an LSD. What's important about a LSD is that one needs to add LSD additive to the Gear Oil when changing the differential fluid (should be done every 30k miles in the Rodeo). If your differential fluid (gear oil) is too old or missing the additive, the LSD can act up and cause a grinding noise during tight turns. Before you do anything else, change your differential fluid. It's easy, cheap, and my problem went away as soon as I did it. Hope this was some help.
