#124 of 160 Upper Sterring Shaft Assembly by seabuckle Mar 31, 2008 (9:43 am)
Anyone got a comment on replacing the standard sterring assembly with the aftermarket zero-play needle bearing U-joint unit from LMC and others? I have an 04 Sierra - had the sterring shaft "exercised" once under warranty. Although the clunk sound went away, the first turn of the wheel each morning still has that not solid feel.

is the wierd looking tip on the 08 duramax important to the system or can i change it to come out the side of the truck so i can use a skirt to tow with. it looks like it necks down a bit maybe for back presure for the cleanburn exhaust Replies to this message: bpari005 (May 04, 2008 8:47 pm) dmaxchic (Oct 14, 2008 2:05 pm)

Replying to: powderal (May 03, 2008 3:11 am) It is a part of the new 2010 emmissions system on the chevy duramax but it is more for the sound than anything else. replacing or removing it would not effect the performance of the truck. I would not mess with any of the rest of it though all kind of sensors are tied into the exhaust on those new models and I'm sure a dealership would love to charge you an arm and a leg to fix it.
#127 of 160 Adding 2-Way Radio Antenna to Silverado 2500HD by wcviper Jul 02, 2008 (10:10 pm)
I have a 2006 Silverado 2500HD. I need to install an antenna for a 2-way radio and be able to place the coax connector in the cab of the truck.   Can anyone suggest the best method of running the coax cable from the antenna mount located close to the hood spring on the drivers side, into the cab?   Does it need to be run through the firewall? Do I need to drill through the firewall to do this or is there a place designed for third party use?   Is there a way to run the cable underneath the body and up into the cab without drilling through the firewall?   Thanks!

Replying to: wcviper (Jul 02, 2008 10:10 pm) You're saying you're going to mount the antenna on the front grill or the hood? There are cables and wires that run through the firewall that you could use or come in through the bottom of the cab via the plugged drain holes. Or drill a new hole and use a grommet.

Replying to: mrual (Jan 05, 2008 11:02 pm) After 6 months of use, remove your intake tube and inspect your throttle body. Buy a couple of cans of throttle body cleaner from Checkers, couple of old rags and have a go at cleaning all that gunk that's going to be in there. If it is really bad you may have to remove the throttle body to clean it.

Replying to: mrual (Jan 06, 2008 11:15 am) By installing the K&N FIPK and a PV catback system one thing I gained was noise. Add to that a set of headers and the truck was dam loud. After awhile it got tiring and mileage increase was non existant. I would have gained a better mpg by not installing the mods and laying off the gas which made more noise that for awhile was enjoyable. I also had the Hypertech programmer, Granatelli MAF, Magnecor wires......none of which gave me more mpg....   And yes, your throttle body will get trashed. Is it from the K&N oil? Don't know but since I dumped my K&N FIPK my throttle body doesn't get anywhere near as dirty. I guess as we get older the "noise" gets annoying.
