I have a 1994 chevy lumina Euro. I had now front

Do the taillights blow out as soon as you install them and turn on the parking lights ?

Try adding more gear oil first. Probably low. It also could be your release bearings going bad in transmission.Try adding the oil first.

disc brakes work on a clamping principle as you said, on the rear of the lumina the caliper sliders tend to seize causing only the piston side to actuate, you will have to replace these pins and bushings as well, have fun

It Varied in Price for the Parts as Some Salvage Yards Charge more because they Remove the Parts But at Others NAMELY Pick-A-Part Doors are around $50.00 Each, Labor to put them on Should be No More than $175.00

Warped rotors will always shake when on the brakes. You say sometimes, so I would look into tires out of round or out of balance. Also, take a good look for any loose front end parts or excessive play.

This model doesn't have shocks. It damps bouncing with McPherson struts. The front struts can have a new cartridge installed while in place, but it's an involved process. The rear struts have to be removed to replace the struts -- a more involved process that requires some special tools. The struts last a lot longer than shock absorbers, but are not nearly as easy to change when the time comes.

educated guess..flasher units (2) one for signals the other for emerg flashers usually located in fuse block under dash drivers side kick panel , glove box area ..or engine compartment near battery

it should be on top of the battery.

best thing is to put a diagnostic comp and check for any faults!! could be somethin simple like plugs and leads

you should only have 3 wires going to the starter there will be a large black wire possably with a red end, a thiner red wire and a thinner purple wire

the thin purple wire is the trigger wire and goes on the small post on the starter solenoid. \
the thin red and thick black/red will get tied in together on the larger post on the starter solenoid
