Do you feel the rattle in the steering wheel ?

Flyge Francis Mark

Thank you Mr Fox. My E brake cable snapped last year. I installled a new one. Not fun. I get 5 clicks when I pull up the handle. I normally buy the cheapest rotors and pads. That's not a good idea cause my rotors go bad in under 10,000 miles. Next I'll be going with extra heavy slotted drilled rotors with carbon fiber pads. If they don't work nothing will.

The front brake problem is more likely the lca bushings are shot!

And the upper motor mount .

drilled and slotted rotors look cool but won’t fix the issue, swap over to larger diameter SS non Brembo rotors

best update ever! And adjust those rear drums , every oil change

The reason your rotors "warp" is the rear brakes are not doing their work (in the physics sense).
More often than not what people perceive as rotor warp is actually LCA bushings.

I replaced both LCAs with new a few months ago. I do need to replace the rear brakes. They are getting low. . So I'll replace the years first see if that does anything for the rotor warp feeling problem. But that still leaves me with the steering rattle which I hope the intermediate steering shaft replacement will fix. Thank you sir!

Lots of good info coming in. Thanks guys! SS Rotors. Check. I don't care about the looks as much as I do drivability and performance. Upper motor mount check! I'll get new rear brakes...should I replace the drums or just the shoes?

the upper engine mount is easy to check, look through the oblong hole in the passenger side front wheel well , see the bolt head in there, it for the serpentine belt tensioner, if you see that in the centre of the hole the mount if ok, if it’s down low in the hole , and you could not put a socket on an extension to that bolt , the compound in the mount has deteriorated enough that it done, replace that mount

Do I "FEEL" the rattling in the steering wheel?
Yes and no. I hear it coming from somewhere under the dash in the area of the column. My wheel doesn't shake back and forth. But a slight vibration resonates in the steering wheel. Slight but noticeable
EDIT! OK. I took it out for a ride. I love being retired. LOL. The wheel DOES shake back and forth when braking at 35 and up
It doesn't matter if I'm straight or on a curve. The wheel still pulses. The only oddity is when I brake straight I get the wheel pulse and rattle noise from column area. When I brake on a curve I get only wheel pulse only. No rattle noise.

These lca rear bushings weren’t very old, GM parts . I replaced them with a Moog problem solver bushings

I am having the exact same issue. New LCA's, new tires, brakes are good. I am going to look into replacing the steering shaft.
