Hi there. i have a 1997 mazda rustler 160i. i have replaced wheel bearings including hubs on my vehicle. i did approx 3000 km and now the front wheel bearings are noisy... can you pse assist with some help...
O.k. ... this is gonna hurt your wallet. replace inner and outer cv joints (might as well do the gearbox oil and seals on shafts while your at it) and do both wheel bearings. Try fitting Timken bearings, they are expensive.... but you get what you pay for.

If you are mechanically inclined, start by having a multimeter connected to your battery. Then, remove fuses one at a time while checking if the draw goes away. This will isolate the circuit and then you begin checking components within that circuit.
An ignition coil is more than likely your problem. When the car is not running pull one spark plug wire and a plug and insert plug into the wire hold plug end on ground area. Have someone crank engine and check for spark. If no spark, replace ignition coil.
Before servicing the vehicle, refer to the precautions in the beginning of this section.
NOTE: The wheel bearings are not serviceable. If the bearings are bad, a new hub/bearing assembly must be installed.
Remove or disconnect the following:
Rear wheels

Brake drum, if equipped
Rear caliper and rotor assembly from the hub, if equipped
Hub dust cover
Raise the staked portion of the hub retaining nut with a hammer and chisel.
Remove or disconnect the following:
Hub retaining nut and discard it
Hub and bearing assembly from the spindle

To install:
Install or connect the following:
Bearing assembly on the spindle. Torque the new nut to 131-173 ft. lbs. (177-235 Nm)
WildBill49 here......Not knowing the specific year and version of your Mazda, I cannot give you a specific part at fault, but I can help you. I am assuming we're talking about an electronic distributor single coil ignition system
If the spark is weak directly out of the coil (with a known good coil hooked up with correect polarity), then the problem is in the spark trigger module... There is a variety of designs, but the basic components remain the same. This is the part of the ignition system that replaces the breaker points. It consists of two parts - a magnetic spark trigger sensor, and a spark signal amplifier/controller. these are sometimes combined into one ignition module.
Replace this module, and spark from the coil should be strong! If it is still weak, reverse the two wires to the coil.
Weak spark at the plug wire with the above good indicates distributor cap/rotor replacement time...
Gerrie, I hope this is what you are looking for, best of luck, and if you feel my advice worthy, please rate it!!!
