Getting intermittent vibration at 40-50 mph. New u-joints( vibration there b4 they were changed ), all tireshigh spd balanced, front susp. parts tight, c/v joints &amp; front drive shaftok too. Engine scan ok also. Could this be a problem w/ lock-up torque converter, is there an adjustment I can make, or is there something in transfer case causing this?</P>


Thanks,</P>

I had problem similar but mine was the front wheel bearings have you had those looked at have you done ujoints all the way around main and 4 wheel shaft . also you said tires were ballanced but what about a slight seperated belt in one of the tires . the ballance machine won't pick that up. just a couple thing i could think of</P>


I don't really think the case would do it not much in there to go out of ballance</P>
