Replying to: diablo3 (Jan 08, 2007 3:15 am) Have to read the codes out with a tech 2 scanner first to confirm. If in salt use areas the rust builds up and raises the sensor out of spec so have to unbolt the sensor and carefully sand the mating surface and not get any crap in the hole and in the hub, if thats the problem. Check the wires from the sensors up to the connector on the frame for cuts first on the fronts. Rear sensor is on the trans 2wd and transfer 4wd. Hub bearings (one piece asembly)going may also cause this but you would hear it also normally.

Replying to: painhead (Jan 24, 2007 5:05 pm) Specifically for those 2 codes no but heres the circuit descrition form the odb-codes site:   This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine. Symptoms: You likely won't notice any drivability problems. Causes: A code P0440 could mean one or more of the following has happened: The gas cap is not installed or working properly The purge solenoid has failed The canister is plugged and not working properly Replies to this message: painhead (Jan 26, 2007 9:10 am)

#18 of 39 98 envoy abs by bigdaddy81 Jul 15, 2007 (4:22 pm)
i have a 98 envoy. about a month ago my drivers side front hub went out. went to autozone and purchased a new one installed it perfectly. now about a month after the abs light came one and stays on. took it in they told me it was the speed sensor and the wiring harness as well as i need to replace with updated hub. what of this sound right?. hubs new and it appears to have speed sensor permantly atteached. on the oem hub the sensor was removeable. also what can i expect when it comes to replacing my intake manifold gasket on this rig Replies to this message: repairdog (Jul 16, 2007 3:01 pm)

Replying to: bigdaddy81 (Jul 15, 2007 4:22 pm) You must of gotten the El cheapo deluxe hub - if under $150-200 (2wd more) you did. The Timken are good and the Advance BCA hubs. Return it as trash and get the good one (looked up the cheapo and had a 3 month warranty)- most fail within a year.
#20 of 39 98 envoy abs by bigdaddy81 Jul 16, 2007 (4:35 pm)
we paid 152 or 182 for the front hub on a four wheel drive. i didn't go with him to get it he left and brought it back. normally he doesn't buy the cheapest available, is there anywhere on the hub for me to be able to tell what brand it was i am unsure if we still have the reciept.

Replying to: bigdaddy81 (Jul 16, 2007 4:35 pm) No clue but the warranty is in AutoZ computer so call them and ask.
