driveshaft question
 

my car shakes alot when i drive and when im at high speeds and i put it in nutral it feel like its gonna break apart. then i looked under my car today and it seems that my driveshaft on the u-joints are broken. not like alot but when i move it up and down with my hand theres like half an inch of free-play. can i just take out the driveshaft and fix the u-joints or should i just get another 1??

a local should should be able to weld on new UV joints & re-balance the shaft. Otherwise check the local salvage or check www.mazmart.com or www.mazdarecycling.com .

stop driving on it! if it breaks while your driving, it can take out your tranny with it- happened to a friend of mine. replace it asap
