[QUOTE="cobralvr01, post: 15345045, member: 164560"] So some of you guys may have seen in these threads that I finished an IRS swap recently. I've recently been experiencing a clunk noise when shifting while both at a standstill and cruising. I also have alot of drivetrain noise going on while going 40+mph. I just checked a couple of nights ago to see if anything was loose. Sure enough, ALL the subframe bolts were loose probably due to the unit shifting into place. I tightened those down as much as possible. I check the front pumpkin bolts and they were somewhat loose too, so I tightened those down to spec. I checked for anything else that may be loose, but there's nothing left. I didn't adjust the driveline angle. I was able to mimic the clunking sound by raising up the rear end, lying down right in the center of the car under the gas tank, grabbing the wheels on both sides and rotating them back and forth. It sounded like it was in the center pumpkin and continuing into the drive shaft. I have an aluminum driveshaft so the sound is very pingy and loud. Is this the infamous Terminator clunk sound I'm experiencing? If it is, is there any cause for concern or any ways to get rid of it? Could it be my driveline being out of alignment that would cause this? IRS Specs: [U]Terminator #1 30k miles:[/U] Pulled IRS unit DSS Level 5 half shafts (removed because they're too robust for my application) blown up center pumpkin FTBR delrin bushings on control arms, subframe, front & rear diff mounts. [U]Terminator #2 30k miles:[/U] 1 cv axle (replaced 1 DSS halfshaft) New Ford Racing bearing [U]Terminator #3 50k miles:[/U] 1 cv axle (replaced 1 DSS halfshaft) New Ford Racing bearing [U] Terminator #4 30k miles :[/U] Center Pumpkin (never cracked open...I put in new Royal Purple fluid in as well) [/QUOTE]
