Passenger Side Rear End Noise
Hey guys,
I did a search on the 3rd Gen Current and Archive boards and couldn't find what I'm looking for. I'm probably not searching on quite the right thing.
I've got a knock that comes from the rear passenger side, very near the wheel. When I'm rolling very slowly up to a light and tap the brake, I hear this knock. If I'm on an incline and can keep rolling, I'll hear it every time I tap the brake. The knock is just a little bit hollow. Seems like maybe I'm hearing it transmit up through the body a bit.
Any ideas? I'm guessing bushings of some sort, but I really don't know my way around down there. I'll probably pass your advice to my local mechanic. I need your help in being able to speak the righ language. If it turns out to be bushings, any recommendations on what to install while I'm down there? Its my daily driver, just looking for good quality to keep here running smooth.
Thanks,

Ya man..I have the Same problem!
It is your rear bushings... probably on your control arms, and maybe other places. the passenger-side rear bushings usually go out first on FD's, so your case is not something unheard of. I believe mazda only sells the bushings already installed in the coltrol arm because they are sealed bushings. Rotary performance can swap out bushing without making you buy new controll arms/ tie rods/ etc. I am sure some of your local suspension shops or RX-7 shops know how to do this also. I think it is costing me somewhere around $630 for them to fix mine. Are ou getting wheel hop and decreased handling when you launch and take turns sharp since this noise has started occurring???

Not the jack. I don't have it in the car. You can hear it every time you just touch the brakes (not hard enough to jostle anything around in the car).

I've got a new clue. What's the chance that the sound I'm hearing is actually coming up from the U-joint or the diff? Just today, I'm hearing a substanial knocking or pounding that is rythmic and increases and decreases in direct proportion to speed.
What do you look for on a bad U-Join? And on the diff, how much play should I have in the trans-axle. I had the wheels off last night and it seemed like the lug bolts were rotating about 1/2 inch or more before I could here the stop inside the diff.
Thanks,

I have a bad front CV Joint on my Acura Legend (1988). When I turn the wheel, I hear clicking (very obvious). When I am driving straight, not a bit of noise. When I slow down and step on the brakes, you can hear the clicking (faint, but noticeable). Sounds like your noises are the same as mine. I know for a fact that my CV's are bad since turning the front wheel turns the CV joint. With the RX7, the wheel does not turn in the rear, so you would not notice the obvious quickly.

Seems like it is the passenger toe link then. I was all over the suspension when I changed the struts and the toe link was the only thing I found which moved. Perhaps under load some of the other stuff is also worn, but the link was obvious.
I think the toe links are cheaper from Pettit at $200 a pair. I think this is the way I am going.

My car has the same problem and I'am thinking about getting the toe links. How much are they from M2 and can this type of work be done with jack stands with hand tools(no air powered tools)?

i forgot i own an FD
I'm having a very similar problem as the original post, but I only get the clicking noise the 1st time I tap the brakes. After completely stopping and rolling again, it will click the first time I tap the brakes, but not after that until I stop. I can't tell where it's coming from. Is it my bushings???
