Vibration Problem Solved

[thunderX]

After replacing my transfer case chain, noticed a strong vibration from 22 mph - 28 mph that shook entire X5, making it impossible to accelerate normally. Since it was very strong at the center console, changed the Center Support Bearing with only a little improvement. Next replacement was the transmission mount with only a little improvement. Next was the motor mounts with also only a little improvement. Got rear tires balanced, which were 3 oz off and saw a good enough improvement that acceleration was now possible but the vibration was still there. Next up were the worn out rear ball joints- the inside edge wear on one tire was the giveaway. This almost got rid of the vibration but it was still there.

The fix? Replaced the subframe mounts. While the 2 fronts were destroyed the 2 rears were still in tact. Instead of OEM got polyurethane. Haven't experienced such a quiet rear in years!

Hope this helps others, this site has helped me quite a bit.
