So last night i take off from a light and hear this kinda loud spinning noise coming from the under the reaer of the car.It started doing it when i got on the gas at about 25-30mph.It only does it if im moving.Sound like u-joints?How do i to tell if there bad?

[PhillyGT]

I just went around the block a few times,to try and replicate the noise.Now i can barely hear it.I tried listening for clicking but i coldnt.How much do shops carge to put new ones in?

[93hatch]

theyre not hard at all to put in dude, just need a hammer

[PhillyGT]

How can i tell its
definately them

Wouldn't it make a noise at all speeds if it is the u joint?

[PhillyGT]

Thats what i thought.I was looking on the interwebs,and found some things about a "center support bearing" making a whirring,spinning noise.Now what the hell is a center support bearing,and where does it go?

[95StangMX]

center support bearing could be your problem if you say its a spinning noise, a u joint would be more of a clunking sound when you take off or switch gears, the center support bearing is on the drive shaft it drops down from the floor of the car and holds the drive shaft in place (supports it)

[PhillyGT]

Its not clicking or clunking at all.Whats something like that cost??

[95StangMX]

about 15-20 bucks at autozone, and do it yourself, its super easy.

Sounds like either u-joints or pinion bearing..
Get under car and see if there is oil leaking at pinion seal, that's first sign of it going out....if not, twist driveline back and forth to see if there is slop in u-joints. You may have a dry joint.

i know im a noob,but is there a how-to online?Also how can i tell thats reall the problem??

Do foxs have this? My driveshaft is held between the transmission and read end. I dont think 1-piece driveshafts have this

Just jack up the car and take a look....or get help from freinds...

And no...1 piece drivelines do not have carrier bearings...mostly used on longer wheelbase cars/trucks...like older station wagons and long bed pickups.

no foxes do not have this.

if you have a high frequency viberation, I'd say it is the u joint. If you don't have a vibe, I'd say that a bearing in your rear (most likely pinion bearing) is spanked.

I was at a red light and i thought it was running shitty,then i punched it and heard that whirring spinning noise.After about 25mph i heard it going with the rpm's.

[HotRodJosh]

Check the rearend.....sure sounds like pinion seal or rear cover leaked and now yer outta oil....and the sound would be the ring and pinion mesh without oil.....the pitch of the sound will change with rpm...

[PhillyGT]

Sounds logical.Shes going in zee shop monday,so i can it taken care of.I checked the cover and it does look like it leaked.It looks kinda old though.

[95StangMX]

Didn't think a fox had them, but he said someone said carrier bearing. I simply explained what and where

[PhillyGT]

Its all good
