Thanks geo
Pretty simple huh? That clip can be a pisser tho. !
Lucky it wasn't a Caddy Northstar cuz you have to
loosen up the fuel rail(s) to get the clip in right.
Then make sure the fuel rail and o rings are seated
properly.............
Easy and cheap fix...........Just think if the dealer
had it and started throwing $pendy parts at it !!!! :sick:
Do you have a tilt wheel?

GMs torque mgmt. program.
The 4.8 and 5.3s run like scalded dogs compared to the 6.0.
Till ya put 10k lbs. behind it !!!!!!!!!!
My buds bone stock 04 5.3 x-cab 4x4 will run circles
around my 04 2500 x-cab 4x4 and I have a Hypertech 3
tune loaded into it !!!!!!!!!!
10 mpg....Thats about right ! Imagine if ya had a 8.1 !
FINALLY got some snow today in Syracuse ! Got to work that
truck.............
Yea.......Goofing off in NJ! Sunshine and birds singing down there................
Thats why I am the "bar and travel consultant" over at the snowplowing forum and NOT a moderator !!!!! :P
$ 2K to change one set of pinion and ring gears appears outrageous to me. Even if your truck is 4 WD and two sets of gears required, it is still high. Years ago I remember I wanted to change the gear ratio on my 1985 Mustang GT and I was quoted something like $ 400 by a Ford dealer (parts and labor).
Perform a simple test to see if you in fact have 3.73 gears. Jack up the rear axle at the differential, place the vehicle in neutral. Mark one wheel and driveshaft with masking tape for a reference point, then count the number of driveshaft turns required to get one full wheel revolution. For 3.73 ratio gears, 3.73 revolutions of the shaft will produce one full wheel revolution. You should be able to do this test fairly accurately.
I hate to break it to you; My 8.1L gets 12+, mostly highway. If I do a lot of stop & go it'll dip into the 10's. You should be getting better, 14-15 mpg at least. Somthin' idn't right.

Thanks
round 2 with gm, problem came back turns out it is corrosion in the fuel line. they still will not return money, the gm rep states that something in my fuel caused this problem. this is what the service manager states but will not let me speak with the rep. anyway can you give me the name and number for the dealership you went to.
thanks,

Many people adjust the torsion bars to raise the front end or buy new torsion bar keys (reindexed keys affect how stiff the torsion bars can be set, allowing for greater hieght increases). "Ford keys" are a popular internet search term for owners doing this. Keep in mind that the torsion bars are the actual springs for the front suspension so tightening them to raise the front stiffens the suspension and can affect the ride quality. There has been minor debate as to whether this change affects the longevity of the front suspension too, but so far I haven't read of anyone actually having anything break. Some owners consider the fuel efficiency change or ride change to be a non-issue, especially considering the "leveled" look they're after, so it's entirely a personal issue. Search the internet for more information on what's involved for adjusting the torsion bars.
Kits are also now available. These usually include longer shocks for the front to compensate for the increased suspension travel and a set of reindexed keys among other things. Some include a complete 4 shock setup (to match the front and rear) while others offer just replacements for the front. I've only seen them on the market for the past several months and haven't seen any feedback from others that may be using them.
Think of it like this - what RPM does your truck shift at (1-2) when you are empty - now fill the bed with rocks - I bet the shift point is now higher. Replacing the 4.1 gears with 3.73 is making your engine work harder all the time - just like you have rocks in the bed! So the difference between these gears and the change in MPG will be very small.
If you still don't agree - take a bike that has adjustable gears. How hard is it to get going from a stop if you are in 5th gear compared to 2nd gear?
I've done searches and have come up w/ lots of discussions re: the Allison transmission acting badly in the cold. I also have a GM notice saying the same thing (and that this is by design). But is this acceptable?
Several times upon stopping my truck will slip into neutral or feel like it is almost neutral (slipping). This allows me to get through the intersection but seems to me this is something I shouldn't have to be concerned with. Not sure it is just an issue of letting the vehicle warm up. After this happening, I decided to take the truck to the dealership. For 12 miles, the vehicle did not shift out of first. Shouldn't it have been warm enough for this not to be the explanation?
Then today, I took delivery of the vehicle from the dealership. The temp gauge had registered an increase. The first stop and start resulted in the slipping. After about 20 seconds of coasting, the vehicle violently shifted up. Had a service guy w/ me in the vehicle and he agreed to take it back. Not sure what they'll come up with since they've already had the vehicle for several days.
Any ideas what is going on? Help/advice appreciated.
-BTW- Would you please post the links to the discussions you mentioned above. Thanks.

There was a new TSB put out recently about Tahoes / Escalades / Suburbans / Silverados --- and Fender bushings.
The dealer removed my driver side fender and hood, then adjusted the fender 1/16" forward when placing it back onthe truck. Apparently, when the fending is "seated" prior to tightening the fasteners, the fasterners themselves shift. Although there was NO INDICATION that the rattle / clunk / pop was coming directly from the fender ---- low and behold, simply taking it off and shifting it slightly forward before re-fastening, made all the difference in the world. The clunk / pop / rattle I've heard for over 8,000 miles appears to be gone.
All this after a new intermediate steering shaft, front shocks, body mounts --- all failed to fix the problem.
Well, lets hope this is the permanent fix.
