My 06 makes a weird thumping noise coming from the front of the motor only at startup and not all the time it only lasts a couple of seconds. I removed serpentine belt and started and I dont hear it . any suggestions?

Possibly a bearing going bad on one of the accessories; water pump bearing, A/C bearing, power steering, or tensioner. You need to pinpoint this ASAP.

It's just a SUPER-DUTY Mustang GT Sedan. 198K miles and still rolling HARD.

1997 Crown Victoria P71 SVT *** ex-US Marshall service (the CAR)
STOCK?? I bet it was modified.

13.26 @ 107.24 MPH 1/4 mi w/ me, tools, & full tank of 93 octane

I added CAI, NICHE 19 X 8.5 " wheels with 245/45ZR 19 rubbers, and completely rebuilt the front end with poly bushings, Kooks headers, 2 1/4inch exhaust, TCI 2200-2400 rpm Stall converter

.PLANS:: engine upgrade, 5.4L 2v stroker, rebuild interior in leather w/ buckets, thinking about turbos

thanks, It's a tough one yo pinpoint I'm actually hoping it gets worse so I can find it. not sure of any other way the bearings seem fine when I manually spin them, would be great if it was the tensioner.
