#75 of 449 Chevy Pickup bounce by harvell Apr 05, 2005 (5:33 am)
In december of 2001 I brought a 1999 C/K 1500,extra cab, short bed, old body style with 54,000 miles on it. It has a bounce in the back wheels at 35-40 mph. I have 3 sets of wheels, 2 sets of tires, 2 sets of shocks and had the drive shaft balanced. Please help...

Replying to: plcattle (Apr 04, 2005 8:52 am) Have you checked the U-bolts that mount the axle housing to the leaf springs? It could be that one of the nuts is a little loose.

Replying to: quadsteer (Mar 29, 2005 7:43 pm) I have an '01 2500HD 4x4 EC 6.0 with 4.10 rear end. It has about 45K miles. It is basically stock except for 285/75/16 mudders on American Racing 16x8 aluminum rims. I recently (about 4 months and a couple thousand miles ago) purchased the Hypertech programmer and powertuned for 87 octane fuel. I raised the max speed limiter, changed the automatic tranny shift points and firmness. I did notice a difference in performance, but it was mild. It basically seemed to restore the power loss that I experienced going from the OEM 245/75/16's to the 285's. It just seems to have a little better throttle response. I have also noticed that the tranny doesn't seem to shift as often when pulling. I also noticed about a 1 mpg increase in fuel mileage, (taking into consideration the fact that my speedo was off before reprogramming). To achieve maximum horsepower from the Hypertech, they recommend powertuning for 91 octane (for '01 models, the programmer allows for either 87 or 91 octane - I haven't checked what is available for '04 models) and changing out the stock 195 degree thermostat to a 180 degree thermostat. I did not change from the stock thermostat. It ain't no supercharger, but I am happy with the results I got and don't feel like I wasted $350 (including tax). Hell, at $2.25 per gallon, it should pay for itself in 25K miles. Go to Hypertech.com. They have some very good information on their product, including detailed instructions for reprogramming. It is extremely easy to do and allows for reprogramming back to stock if you need to take your truck into the dealer (this is very important since the dealer can screw up your reprogramming capabilities if they read the on-board diagnostics and download any changes into the computer). The whole process from powertuning to going back to stock takes less than 15 minutes. I don't have any experience with Superchips or any other reprogramming products, but I have heard stories about having to remove your computer to send it in to get reprogrammed. I am currently looking at a Flowmaster dual exhaust system, more for the sound than any additional performance gains. BTW, if you want smoke from the tires when you take off, hold those huge brakes on and gas her. I can turn a cloud of smoke with the 285's until you can't see the back of the truck. I can get a little bark stomping it from a dead stop, but nothing like good ole' powerbraking. Its also nice not having the truck shut down when the speedo hits 97mph (occasionally!). LOL!
#78 of 449 unsure by weaver3 Apr 06, 2005 (7:18 pm)
Having trouble figuring this out: I have a 92 Chevy 1/2 ton 4x4 pickup with a 350 motor. The problem i am having is the truck runs fine when it is cold after the temp rises to proper operating temp the truck dies after about 10 min at idle. the truck also seems to want to die when the accelerator is applied to aprox. 1200 rpms. but above 1200 rpms seems to do fine. No check engine light is on. it also has a new fuel pump and filter. after the truck dies it acts as if it were flooded out and will not imediately start back up. after about 5min the truck will fire up run for 5-10 mins and die again. still no check engine light which seems weird. I have also checked all connections to fuel pump inside and outside the tank all seem to be fine, and the pump operates fine.

#80 of 449 Front Hub Assembly by duramax Apr 08, 2005 (10:00 am)
I have a 2001 chevy 4x4 Duramax crew cab 2500. I bought it used and love the truck, but I have had to replace the front hub assemblies twice within 30,000 miles. I dont drive it real rough, but I do use it on the farm. I was just curious if anyone had any ideas on this. The assembly is around 300 dollars a wheel. The chevy place just tells me it shouldnt be happening.
#81 of 449 87 C20 305 fuel supply issue by bobwriter Apr 09, 2005 (6:23 pm)
Just rebuilt the Electronic Injectors (the not-quite-fuel injection, not quite a carb) and re-installed. I get no fuel flow despite a new filter and fuel pump. I think I may have accidently disconnected some line that tells the fuel pump to work and now cannot find it. No luck as most Chilton's wiring diagrams suck big time. Engine will fire and run if I pulse starting fluid thru throttle body so problem is definitely no fuel pressure. Could use some help here. Are there any sensors or relays that may be bad on this baby and if so where are they? Secondarily, I get a 'system not responding' when I try to read and reset the codes, any ideas on this one?
#82 of 449 1990 chevy 4x4 fuel problems by ericsbaby Apr 10, 2005 (12:35 pm)
The truck i have has a 350 motor. Recently we just had to replace a fuel pump filter and tank. Now when you turn the key on there is no gas coming out of the injectors. But then when you turn turn the key off gas starts coming out of the injectors. Could there be a wire or relay somewhere that we have'nt checked? P lease help i am about to junk it out . But it is a really good truck. Replies to this message: mhadman (Jul 09, 2005 1:34 pm)
#83 of 449 Right taillamp not working properly by hoosierhand Apr 11, 2005 (5:54 pm)
Hello Folks, I've a 90 C/K Pickup - standard cab, long bed. My taillamps were not functioning properly. Replaced all 6 bulbs. Some work, some don't. Decided to do some research. Discovered that the taillamp holder assembly corrodes and is a common problem among these pickups of certain years. Replaced BOTH right and left taillamp holder assemblies. Now they both work just fine. Still have one problem!!! The right taillamp - all 3 lights come on with no problem. The center bulb (the one that acts as a taillight, brake light and turn signal in one) - works fine except it won't light up when using brakes. Won't flash the bulb when using turn signal. BUT it will come on as a taillight. What to do?? The left taillamp works perfectly... brake light comes on, turn signal works fine. I figure it could not be the brake light switch since it works on the left. Could it be turn signal switch? Relay? Please help. Thanks, Jason
#84 of 449 Just so that we don't get too scattered... by kcram HOST Apr 13, 2005 (5:30 pm)
Starting in 1988, the full size Chevy and GMC pickups (while still maintaing their C/K body codes) were named Silverado and Sierra respectively. If you're referring to a 1988-2005 truck, you should be checking the Chevy Silverado: Problems & Solutions and GMC Sierra: Problems & Solutions discussions for more pertinent information. This specific forum is intended for 1987 and earlier C/K trucks. kcram - Pickups Host
