I own a 90 convertible N/A,
The car drives fine around town, But at higher speeds 50+ mph or just under hard turnng at 40mph or so when turning a corner only to the right the passanger front wheel starts shaking/wobble..
The car is fine turning to the left tho..
If anyone can help I would be very thankfull, I took it to midas and they couldn't help me, I really don't think they had too much of a clue about anything..lol

Sounds like a bad wheelbearing, but could be a lot of things. Does is make any noise, if so, what kind?

its either a bad wheel bearing or lower ball joint, both easily repairable. The wheel bearings can be a pain to remove from the hub because mazda made them to be non replaceable but if you read the write up on mazdatrix its fairly easy to replace them yourself but if your not a mechanical person then it would be wise to take it somewhere to get done.

it's a bad wheel bearing!...go to mechanist!....

had a similar problem, just tightened the nut on the wheel bearing, now is ok.

that nut has a specific torque spec that it must be tightened to otherwise the bearings will be toast in no time..this nut should not be tightened very hard i think the specs are only like 25ft lbs which is not much at all..

True it doesn't take much torque but being too lose can be the problem. Proper way I suppose to be 100% sure would be to talk everything apart (inner bearing grease seal should pry loose easily if you pick the right spot), remove both outer and inner wheel bearings, clean the grease off with mineral spirits or similar, let air dry, inspect the rollers for chips burs warping etc. (replace bearing if so), re-grease rollers with a grease gun or mashing bearing into a pile of grease in your hand, messy excess is fine/good, lightly grease all other non-roller surfaces with finger so bearing is fully covered, re-assemble and then tighten (but not overtighten) the nut on the wheel bearing: IIRC keep loose, spin wheel, tighten while wheel is spinning, loosen only a little so it can spin, spin wheel, tighten some more while wheel is spinning, repeat until it won't tighten any farther with light force. Replace the cotter pin on the nut cover with a new one. Install remaining parts including wheels. Check to see if the wheel will tilt (camber direction, not toe/steering). If it will then you didn't tighten the nut enough, go back.

the nut was loose enough I could turn it with my fingers = too loose
