maddzz1 Posted March 17, 2008 Share Posted March 17, 2008 89 4.0 4wd My driver side front started making a noise tonight. At first I thought my engine was tapping/knocking. It doesnt start until I get to about 20mph and stops when I apply the brake? Link to comment Share on other sites More sharing options...
Wildman Posted March 17, 2008 Share Posted March 17, 2008 Like a tapping / Ticking noise?? Check the axle u-joint. Also check to see if your brake pads are in good shape, and the caliper is moving freely. At worst, it could be the wheel hub. Link to comment Share on other sites More sharing options...
dragonrider477 Posted March 17, 2008 Share Posted March 17, 2008 the brackets that hold the brake pads are worn allowing the pads to move around and rattle.the noise is usually worsened when the rotor is warped a bit because every rotation of the rotor will lift and drop the pads making it noisier.stepping on the brake stops the noise.besides expensive new parts,there is no cure for this.i am of course assuming that your wheel bearings are not hosed as that would cause this too.

I have to disagree,,, they make springs that snap to the caliper to hold the pads and keep them from rattling... Link to comment Share on other sites More sharing options...

At worst, it could be the wheel hub. yes it was a tapping sound like when you have almost no oil in your engine. I checked my oil first and it was low ( i have a leak) and thought I had messed up my engine. But after driving around the block 10 times I'm pretty sure it is coming from the wheel. I am going to pull it apart tomorrow, just wanted some ideas on what to check. How do I check if my wheel hub is bad? Link to comment Share on other sites More sharing options...
jtdesigns Posted March 17, 2008 Share Posted March 17, 2008 jack it up and wiggle the wheel and see how much it wobbles... it should rock a tad but not a whole whole lot. Link to comment Share on other sites More sharing options...

Good thing i just bought a new jack and jack stands :roll: :mad: Link to comment Share on other sites More sharing options...
Oizarod115 Posted March 17, 2008 Share Posted March 17, 2008 in a wheel bearing, the only good play, is NO PLAY. you don't want any noticeable movement. Link to comment Share on other sites More sharing options...

I think my brake pad is moving back and forth. The top where it has like a hook to hold it in the caliper. If i move it back and forth it makes the same noise. I have never done brakes before. Can I replace the pads without having to bleed the system? Should new pads fix this or is there something that holds the pad from doing this that i need to replace?

mvusse Posted March 17, 2008 Share Posted March 17, 2008 Never done brakes on a Jeep before, but disc brakes are disc brakes. 1. Yes, you can replace pads without bleeding the system. 2. You should also have the rotor turned, or buy a new one. 3. You will need a 5" or so C-clamp to push the caliper back in. 4. Always replace brake parts in pairs. If you do one front wheel, you should do the other one as well. If the brake fluid is more than a few years old, the whole system should be bled to replace with new fluid. usually starting with the wheel furthest from the master cylinder, working your way to the one closest, but our trucks have some kind of weird variable proportioning valve at the rear axle that I believe the front brakes go through as well, so that might change the order.

jtdesigns Posted March 17, 2008 Share Posted March 17, 2008 You need to put these back on too.. Its the wire looking things. They hold pressure on the pads keeping them from rattling... <<>> Link to comment Share on other sites More sharing options...
