Recently noticed different valve stem on one of my rims. One being the"flexible" rubber type and the other three appearing to be welded/bolted as if part of the rim. When did manufactures start doing this or is this standard on a 3/4 ton vehicle? Would I have to replace the rim or is this something that can be added to current rim?

I drove it 20 miles since with no problem indicating any problems could it be that it just lost power to the transmissiom?

the brake pedal. this problem has occurred intermittently for three months now. I'm afraid if i don't have it checked out soon it may result in a costly repair.

have an engine code of p0300 multiple cyl misfire, put new wires ,plugs, fuel filter, and checked coil packs for each cylinder, all have spark, checked injector plugs for power all have power,. when first started engine runs smooth, after approx a minute it starts to shake and rumble, when its put into gear gets even worse.if i pull plug wires off of the cylinders on the passenger side any one of them the engine makes no changes. what else do i look for?

when in the off position. they stop blinking when i turn the headlights to the on position.How can i repair this problem.thanks in advance...

what tools are needed ?

dont know how to find short any suggestions? Found P.E.D. fuse link with open eyelet not connected to anything.

I have checked the calipers, brakes, fuses and belt. Could this be electrical or maybe the alternator?

My van started fine this cold day with in 5 min engine cutting in and out during warm up gages, lights flashed before stalled. tried to start engine cranked over and fired. Sat a few hours tried again in nuteral and ran strong till back in park and stalled again. tried reset, took off battery connections Neg & Pos hoped to reset computer codes? Brand new Fuel pump, plugs, wires, module, fresh gas replaced round 65,000 after using diesel fuel. ran good till today has K&N Air filter installed. Cranks but not will start or run

sometimes its flash and the van cut off

Doesn't happen all the time only after it sits overnight or a long period of time during the day.

At 40-50 MPH the steering wheel shakes bad and all steer linkage is tight

I have changed the bulbs in the rear driver side and also the top stop light above the cargo doors. when the car is in drive the driver side rear and front blinker flASH rapidly all appear to be working but the outside driverside brake light is dimmer on the driver side. when the van is in drive and the headlights are turned on the blinkers are not blinking as fast but the interior front cargo light still comes on dimmly when i apply the brakes and when the turn signal is on.
