Be sure to check suspension components. Namely the tie-rods...
Probably i would go for wheel balance and maybe check your wheel bearings rotors will not make it shake because of speed
Warped front rotors...........have the front rotors turned or replaced including the brake pads. Done deal. I have seen rear brake vibrations transfer and feel like the front. Have a service advisor confirm before ordering the repairs done, just to be safe. 98% of the time it's the above though.
check inner and outer tie rod ends
Get you front end aligned, that should take care of the shakes.
Your rotors are warped. Replace the brake pads and have the rotors resurfaced or replaced. Make sure the wheel lug nuts are torqued to specs when the tires/wheels are reinstalled. Over tightening the lug nuts will warp the rotors.ANOTHER ANSWERThe above is absolutely correct, however, heat is perhaps the most common cause of warped rotors. If your vehicle has to stop when there are heavy loads, or if you "ride the brakes" (one foot on the brake pedal while you're driving), or if you have a worn caliper that's constantly putting a little pressure on one of the rotors, there can be a lot of heat generated which will result in a warped rotor.On the other hand, if you've had the brakes replaced, and the PREVIOUS mechanic used a cheap replacement rotor, that may be the cause. Cheap rotors warp easily.
When disk brake rotors get old they usually warp a little, causing disk brake "chatter". Fortunately, the rotors are easy to replace, even for a novice. It will probably cost you around $200.00 to $300.00 to have a shop do it for you. It's common to all vehicles with disk brakes and can be caused when the brakes overheat typically when going down long hills with the brakes on. In addition to the above answer, you may not need to replace the rotors. Take them to a machine shop at your local Auto Parts store and see if they can be turned. If so this usually cost around $10 per rotor. Be sure and replace the pads on both wheels, clean everything up with spray brake cleaner, and lube the slide pins unless they are corroded. If they are corroded very badly, replace them. You have warped brake rotors. You will need a brake inspection. They may find that all you need is resurfacing the brake rotors or they may find that your brake pads are worn out as well, and that you need a brake job. The rotors will have to be measured to see if they have not worn down too thin to resurface. The rotors have to be above a predetermined minimum thickness in order to be safe to use. If they are worn too thin, then they will have to be replaced.
Warped brake rotors. Either machine them (if they have enough material left) or replace them. Don't ride the brakes so much and the new ones will stay true. --- added 09/05/11 --- If it just happens while braking then yes the rotors are warped. However the real issue is that the Nissan Quest has a basic design flaw. The brakes do not cool properly, so if you do a lot of city or stop-and-go driving then the rotors will soon warp again anyway. If it happens at speeds above 20mph then you probably have a tire(s) out of balance. Nissans tend to throw wheel weights with regualr frequency. We generally have the tires balanced everytime we have them rotated. ---
in the power steering resevoir,above the power steering pump..
On firewall, above the steering column On firewall, above the steering column
Holding your foot just above the brake pedal, In case you need to brake.
No flasher, it is a relay above steering column right side, its way up there. If you have one signal, working it is the switch in the steering column! Just replaced mine; it cost $500 for the switch! But it's not hard to change, there's no need to pull the steering wheel. Just remove the plastic cover behind.
