I have this chirping sound coming from the bronco when eccelerating, also when cruising but not as much. I think its the u-joint, even though it looks like its in good shape. Whats the easiest way to fix this?

 

[waltman]

Yes it could very well be your u-joints. If they are serviceable, grease them if not replace them

 

[monkeyhouse]

get a haynes manuel, also try searching othe theads, lots of info out there

 

[Gtndrty]

You can take the driveline out and turn the cups by hand. More than likely you have a got a cup that wasn't getting greased and has rust in it.

I don't think that the '93 bronco has a grease fitting for the u-joint, so would the best thing to do would be to get a new u-joint?

From the factory ALL Bonnco's had greaseable ujoints on the driveshafts. If there isn't a zirk fitting on the ujoint it means 1 of 2 things, either the ujoint has been replaced with a non-serviceable ujoint or the zirk has been broken off. Like waltman said if you can't grease em, replace em.

 

[Konham]

thanks a bunch for the info

Actually I'm pretty sure that no vehicles , let alone broncos came with greaseable u-joints, I could be wrong but I can say for sure the 91 Ranger did not come with greasable u-joints.

ive had three broncos and none have had greasable u-joints on either of the drive shafts two of the three broncos had the original u joints too, maybe there were a few years that had em but i know mine sure didnt

My F-250's got greasable fittings on the driveshafts... :shrug

Also, it sounds like a wheel bearing, not a u-joint.

 

[Konham]

its not a wheel bearing, its to fast of a sound, also it doesnt happen when im just rolling, its when im eccelerating

 

[Konham]

dang, so i prolly do have to get a new u-joint, whats the price range?

Mine went from EXTREMELY fast to not at all and everywhere in between before it blew out. Mine happened when I was rolling slowly, and accelrating...

Check both when you get a chance...

Check www.napaonline.com for the particulars for your truck... when I worked for Napa they went for $25 or so for the good ones.

 

[waltman]

I got a hundred that says it is a u-joint

 

[Konham]

ill put the 25 for the ujoint at napa, i am also hearing another sound besides the chirping, it only happens when excellerating, its like a mild clunking sound and creates some vibration. Seems almost like its coming from the front driveshaft but its when im in 2wd.

 

[Spookshow ONE]

Could your hubs be sticking? Why would it happen during acc? If the hubs are UNlocked, then they theoritically, shouldn't be moving.

 

[Konham]

no hubs are free they work fine, i know that for sure. I'm thinking that if its the front driveshaft that is making the sound than the 4x4 isnt disengaging. That would be bad

 

[Spookshow ONE]

That would mean your TC isn't disengaing sp*... do you have manual or auto hubs?

 

[Konham]

manual, when it was up on a lift i tested both lockers they worth perfectly

 

[Spookshow ONE]

Only thing it could be is the TC then... there is a way to test it but it requires 4 jack stands... you got a Chiltons/Haynes?
