    i'm hearing some sort of grinding sound when ever i let off the skinny pedal. it's more noticable at higher speeds. i'm not sure if it is coming from the T/C, tranny, or rear end.
    Any ideas? Has anyone else ever had anything like this?

    TWO THINGS ON A 205 COULD CAUSE A GRINDING NOISE,
    TOO MUCH ANGLE ON REAR DRIVE SHAFT
    OR
    THE CENTER GEARS OR CLUSTER GEARS (THE ONES IN THE CENTER THAT CONNECT THE TOP GEARS TO THE LOWER SET FOR THE FRT DRIVE SHAFT)INSIDE THE CASE
    YOU NEED TO TAKE IT APART AND SHIM THE GEARS, THERE IS MOST LIKELY TOO MUCH PLAY AND THE GEARS ARE 'WALKING' BACK AND FORTH

    I dont know about on a 205, but on my 208, after I put on a lift, I noticed the same grinding noise whenever I let off the gas. I had to lengthen the driveshaft, lower the t-case, and convert to a cv shaft to fix the noise. I would say, just switching to a cv shaft should eliminate about 90% of that noise.

    I had the same problem when I bent my transfer case mount. It jacked my driveline angles all up. I straightened it out and the noise went away. It was a 208.

    naw, it's a slip yoke. i think i found the problem. i pulle dthe shaft out and noticed a butt load of wear on the yoke. i think i have a blown bushing inside there.
    now i just need to figure out how to replace it /forums/images/graemlins/confused.gif, anyone ever had to do this?
