    And then you will want to punch the engineer who designed it this way right in the throat.

    The dealer told me there was a fix on my vibration and growling problem but because I had a claim with corporate they could not start the repair until corporate contacted them. I asked what the fix was and they did not know. Corporate contacted me and said there is no fix, that the engineer said if there was aproblem it was due to the lift and tire size ( 285/70R17 ) I told them that it started a month after the lift, and the tires were still the same at that time, that desert toyota told me the factory tires were causing the problem. They only had 6000 miles on them and that I spent $ 1600 dollars with no change in the noise or vibration. They did say my truck was still under warrenty. I'm taking it to 4 wheel parts in two weeks and they are going to go through it. Let me add that the service writer and their machanic at Desert said they felt it and heard it, but every time they put it on the rack and give it back, it drives like driving on glass for a 100 miles or so, any ideas???

    Thanks guys, much appreciated. I thought it might be one of those "subtle design failures".
    Thanks again,

    I installed the ECGS bearing on my 1st gen and am noticing a vibration at all speeds but most notably at 60-70 mph. Also when I just lightly hit the gas or decelerate, there is a feeling of something rubbing (metal on metal) on the floor. Is it possible that I pushed the bushing in too far and its making contact with the spline gears? Is this dangerous in any way? None of these symptoms were present until I installed the new ECGS bushing.

    ^^ Yep, you can drive the bushing in too far and hit the spider gears. I trust that you did not check for that with a feeler gauge or something. Oh well, coulda, woulda, shoulda....

    If I were you I would pull the drain plug on the differential and see if tiny metal particles or gray metallic goo stuff is starting to accumulate. If this stuff is growing on the magnet you might be able to save the front diff. by doing repeated changes of the lube and monitor it like a hawk. Drain, refill, drive short distances, repeat. Then do it again and again and again.... If you got larger metal shavings, you got a problem.

    Jack the truck up the turn the left tire by hand and listen carefully for a noise coming from that area. Also, don't forget to look at the brake shield (often bent and contacts disc) and other parts for rubbing.

    Thanks a ton. I didn't mention that I also replaced the cv axle at the same time as the ecgs bushing. Starting to wonder if the reman cv is bad?

    IgnorantlyAlberta and nj636, just wanted to let you know that it was the driver side wheel bearing as you both suggested. Even though the wheel was not loose and there was no noticeable noise coming from the driver side wheel when I turned it by hand. I would of bet a C-note that the noise was coming from the passenger side, but I would have lost that bet. Thanks guys!

    Ok I have a quick question; my truck does not really vibrate, but the steering wheel will kind of "wobble" like someone was moving the steering wheel back and forth about 1/8" to 1/4". It usually happens when I am getting on the freeway at about 55MPH. Does this sound like the same issue?
    Thanks,
    Ken

    You'll know it if you have it. Get under your truck and grab the driver's side CV axle where it goes into your front diff. Now move it, up/down and back/front. There will be alot of play. Try moving it in/out, more play. Now compare it with your passenger side CV. There will not be any play, it is nice and tight there.

    Best advice I can give you is to find a freshly paved street, as these tend to be the quietest and smoothest. If you are listening, you can hear what I can only describe as a vibration, like if you had mud terrain tires. I can actually feel it when I have the stereo on.

    Switch into 4hi when you hear/feel it. It will instantly go away as soon as the diff engages. You won't hear it, you won't feel it. Go back to 2hi, it won't be instant, but as soon as you let off the gas and take the tension off the CV axles, it will be back.

    Thanks again,

    Just to clarify, how far in do you push the oil seal? As far as it will go, or flush with the edge of the diff? I just installed my ECGS bushing a month ago, and now I'm getting a small leak?
