Question about 2003 GMC Yukon Denali
It feels like the front end is heavy. Poor steering and lack of power. It whines until you let off the gas then it stops. Oil pressure shows a little lower at idle than normal. I have replaced both belt tensioners, both belts, idler pully, and alternator. Help!

it is your idler pulley. get it from dealer comes with bracket, just use pulley off bracket. take your belt off and your idler pulley is lower right hand side(facing your engine). 15mm bolt, replace pulley and reinstall your belt. it;s a common problem on trailblazers

the jerking and noise you are experiencing is the drive chain and bearings in the transfer case also you may want to check the end play in both front and rear pinion bearings and yokes
