Loud metal on metal noise when I climb

[Jfeldman702]

So whenever I get my 74 on any steep incline or put stress on the front diff, I get a loud metal on metal grinding noise. I've watched YouTube videos of other broncos and every once in awhile ill hear it on one of them as well. I only hear the noise when I hit the gas. Almost sounds like my hubs, I don't know. Any thoughts on what's causing the noise. Thanks in advance for any ideas. Btw, if u give me ur email address ill send you a video of my bronco making the noise as I climb up some rocks.

I have the video on YouTube. Watch and listen to the sqeeling noise and give me your feedback.

It could be the front driveshaft rubbing on something. Mine sometimes rubs on my crossover exhaust. Anybody available to watch for you when climbing?

It's not hubs, it may be limited slip diff, my bet is front suspension components: drop bar, springs, links

 

[Jfeldman702]

I have full air lockers so i don think its a limited slip issue. Ill check the front drive shaft and see if there is any rubbing going on or signs of something contacting it. Thanks

Sounds like a u-joint to me

Maybe the fan's hitting the shroud.

 

[Jfeldman702]

Checked the u joints. Everything is tight. The whining/metal noise seems to be near the front left. Maybe power steering pump acting crazy when I'm on inclines?

Maybe the fan's hitting the shroud.

Or starter gear.

Sounds like the fan hitting the shroud to me.....

 

[Jfeldman702]

Ok, I'll deffinately get in and Check for any rubbing on the fan. There's another longer video and u can hear it on there as well. If u copy the URL u can then find the other video under my user name 702jd74. Thanks again all

 

[gnpenning]

wondering what you have found.

 

[Jfeldman702]

I haven't found anything yet. Fan shroud looked ok. Check out my video on YouTube. SeArch 702jd74 and it will bring up my bronco. You can hear it in the vids when I'm climbing. Noise happens when I hit the gas. Driving me nuts

 

[gnpenning]

Mine used to make the same sound. Never did find it. Would love to know what you find. Only did it under load going uphill.

 

[Justafordguy]

does it make the sound even if you aren't turning the wheel one way or the other? If it's not the PS belt slipping I bet it's the front drive shaft u-joints. try it in 2 wheel with the hubs unlocked and see if it still makes the noise.

I don't want to highjack or confuse answers here so I will let jfeldman respond. Besides my motor is on a stand right now.

 

[gnpenning]

How are you coming on this?

Sounds like the flywheel hitting a bolt that is either loose, or to long.

Starter bendix bouncing on the fly wheel, shim the starter.
