They just locked up on me

Wheel bearings are bad and need to remove the front hubs

There is no power going to that plug and no fuses are blown

when going about 80 km/hr, speedometer is reading 180...engine seems to kick off...when speedometer drops the engine kicks back on with a big bang. This has just started and the vehicle is not hot or cold

sounds like starter not engaging, just a wiring sound. Computer analizer won't work on van

It is also a diesel. It's not turning over and there is no fuel smell, could it be just the fuel filter or could it be something else. Thanks again.

I really need this repair manual because I want to make a few repair procedures and this would help me in a lot of situations.

This truck has side curtain air bags. Do I have to disable the side curtain air bags to R&R the headliner? How do I remove this headliner without damaging, setting off the side curtain bags?

This vehicle has a 6 liter engine & 4 spd. auto trans., has 164,000 mi. on it. I purchased it with 75,000 from a dealer. Since that time I have had to replace the flywheel 3 times and it needs it again. The last time @ 137,000 mi. the repair shop installed a "spacer" (which it didn't have previously, indicating that's probably why it cracked. Each time the cracks develop at the bolt holes & radiate out. The noticeable symptoms are a rattling or crackling noise at idle, similar to the sound made by the "heat riser" in the older engines. Does anyone else have this ongoing problem.

van will crank, run on ether, no power to fuel pump relay coil circuit,security light not flashing, fuel pump works

what should the fuel pressure and flow be? The vehicle runs and idles but has no power. Does drive but hard to accelerate or maintain speed. Codes are p0101 (air flow) and p0300 (misfire) I have replaced the MAF hoping for the simple fix with the p0101 but no change

While I'm driving so often the entire van shakes, like clutch is not engaging correctly.or the flywheel is unbalance. Any advice?




put in NEW starter. let idle, started shrieking again. didnt blow any fuses this time. (old starter stunk, wiped out.)
pulled alt. no "bad" smell / feel / sound.
no restart after driving 2 miles.
sounds like starter is getting power, with dog box off, but no turnover.
other accessories all spin / smell fine w belt off.
lost here. what causes a starter to cook itself, while driving, and simultaneously wipe out the gear shift indicator box? it only lights in park and neutral.
the whole time, volt gauge and everything else showed normal.

i dont think its just bolt ons. HELP!
BCM?
something else?
cant afford downtime. this van is a work van. Thanks!!

At first it would come on here and there but it no longer comes on now but the fan that runs the heat to rear passenger seats work fine

I've replaced a lot of the electronics and I was told its the body control module
