I have a 92 FD and I'm getting a lot of road noise while driving seems like the suspension. Last weekend i put some new shocks and springs in that i got from a buddy (used) and its a little better but the sounds is still there. If i buy new suspension do you think this will help at all? or anyone have a suggestion on what else it could be i know its not very specific but idk how else to describe it

tires matter, could be a wheel bearing too.

This... What wheels and tires are you using?

i'm slow on the uptake today, step 1 is to rotate the tires, and see if the noise moves/changes. if yes, you have a bad tyre or tire. if no, it is more likely to be a bearing, although it can still be a tire, or a tyre.

a mildly bad bearing and a bad tire sound the same, so its hard to tell them apart

Ok I've swapped wheels and tires completely and the sound is still there so in assuming a wheel bearing in swapping out the rear end next weekend so I'll see if that changes anything

I would recommend finding an experiences technician to test drive your car and evaluate the noise. There is no substitute for experience when diagnosing a noise. Often I can pinpoint a bearing, driveline, or tire noise without putting a car on the lift.

I had the same problem. check the wheel balance. also how are your tires?

i have found the same, once you find a way to make the noise repeatable, either on a certain road, or better yet in the driveway, then the mechanic can make the noise, and find it pretty easily.

after all step 1 in any repair is to duplicate the problem, and the last step is to verify the repair

That's exactly the way it should be done!

Now, If we could only get everybody to do it that way.

Ok so i think it may just be tires but i also found out my back right shock is blown out as well so I'm guessing thats contributing to it as well thanks for the help all

In my experience most road noise is from the tires, particularly in a car like the FD that isn't daily driven. My tires die of old age well before they wear out. As they age and get harder the noise level goes up dramatically. I just put new tires on my FD replacing the 8 year old tires that still looked brand new but felt like hard plastic, it's amazing how much quieter the ride is!

Bearings do fail, but if your tires are more than a few years old I would suspect them first.

you need to put the re-pew pew on the same tires as the FD, so you can use them up

Yeah that's what I need, hard plastic tires on the REPU. It already has pretty crappy brakes, if the tires won't grip I'll never be able to stop! At least road noise from tires wouldn't be a concern.
