almost positive the noise i started hearing is from the front wheel bearings. my exhaust is so loud and with the radio usually blaring i just heard it the other day when i happened to roll to a stop at a redlight with the radio off. its kinda a rolling noise coming from the front... are the bearings press fit on these cars or u can just swap them out in the hub? also while i have it apart is there any other recommendations of other things to change while im in there? ive already done brakes and rotors so no worries there...

 

Pretty simple to figure out what type bearings they are by looking in a Haynes manual or the FSM.

In my signature is the link to the FSM. If you plan on working on your own car you need to have reference to this material. :-)

To answer your question. They are just standard serviceable bearings. Front wheel drive cars have pressed on bearing assembly's. You will need inner grease seals when you do the job.

Question- Did this noise start when you did your brake job? Also does the noise increase with speed?

 

well i have a manual and everything for it. just decided to post on here cuz im bored at work and wanted to know if anyone had any tips or tricks before i jump into it. the brakes were done almost a year ago so i doubt it has anything to do with that. and i cant really hear it at speed cuz the exhaust and everything is so loud. ive tried to push in the clutch and listen while i coast but it doesnt seem louder. i can just hear it better as i come to a stop because everything else is quiet. so i to get some inner and outer bearings and grease seals when i go to oriellys? anything else?

 

You can assume that it is a wheel bearing or you could put it up in the air and spin the wheels and see if there is any noise. Also see if their is any play in the wheels. Then you can remove the bearings and inspect them to see if they are damaged. If so then replace them, if not just re-grease them.

There is nothing else to replace at that time expect maybe the cotter keys if they are damaged. It's a good time to inspect the steering components for play.

 

For years I greased new bearings by, til I bought a grease press. Well worth the 10 bucks.

 

I recently replaced bearings, it was no sweat. The most difficult part was finding the correct torque for the hub. The FSM has a good technique. If there is a significant difference between inner/outer bearing wear, it's time to check suspension parts and/or alignment.

Have fun, and be sure to pack the new bearings correctly.

 

They are cake to replace, take the caliper of, take the hub nut of an pull the disc of and pulle the bearings out, then reverse to put it together

 

i have the inner bearing for sale and the seal $25 shipped for 1984 & 85 lmk thanks

 

If you replace the bearings you should also replace the races or else the bearng
manufacturer won't honor the warranty (not that I've ever had the opportunity to
pursue warranty claims on bearings ).

Seriously, new bearings new races, its just a good practice. The old bearings will
have worn the races and the new bearings will wear faster if the races are not
replaced.

 

I agree. Plus, if you really have bearing damage, I'm sure one of the races is toast too. You may have to get someone to press out the old outer race and press in the new race, but it's well worth it.

 

good deal guys. im tearing into it next week. we have a bearing press and everything so im gonna just change it all out for brand new. ive got 288k miles on the car so id like it to last as long again cuz im sure they havent been changed. it still had the dang stock clutch when i got it and was all original. i destroyed that in like a week tho haha. just fixing one thing at a time

 

pulled it apart today and to my amazement one of the bolts that holds the caliper to the mounting bracket sheered off and the caliper was just kinda laying there. prolly being held on by the 13 inch wheel im running not letting it fall back all the way. glad i caught this now so there wont be a massive fail a few days later

 

You can drive the races out with a punch. To install the new races I use an aluminum race and seal driver from a Lisle kit

I also have a Lisle bearing packer.....one of my favorite tools.

The wheel bearings on an RX7 are small they really should be given a fair amount of attention on a regular basis. On the racecars we service them at brake pad half life or somewhere around the 8th to10th heat cycle. It is not uncommon to see them turning blue from heat.

Always install a new seal when doing this service.
