It's time to play what's that noise!

[CMK720]

Ok, so the story goes I got my gears changed from 3.55 to 4.10s about two months ago. Ever since the gears changed I got this noise, it's really f'in annoying too. What do you think it is?

Got it, sent one back.

Did you do anything else to the car at the time of install, or after?

Nope just went for the gear change.

I would just take it back to the installer, and tell him to fix=it. Don't wait !!! I could tell you what i think, but it would mean nothing. you gota take it back.

Please share, always interested in the results so if it happens to me Ill have a place to start looking!
Plus 4.10s are in the very near future for me, well that or headers and o/r h pipe, probably something I should check when Im under there.

X2^^^ Going 4.10's in a couple of weeks and it would be nice to have a solution to your problem on hand just in case I have the same problem!

That's just the problem even the installer has no idea what it is. They even put a different gear set in There and its Not going away. So I was hoping someone on here could help me out!

ahh the importance of a good gear installer. Thats why Ive used CJ Pony Parts for my 8.8's and Currie for my 9"

 

[CMK720]

Anybody?!

 

[gil_t2]

I am not busting on your installer, but he missed something! Did he reuse any parts, like bearings or crush sleeve? It sounds like pinion bearing loose to me, Could be a DS not seated flush with flange.

 

[NickS]

Some sort of bearing, definitely. Maybe even a wheel bearing.

 

[CMK720]

I was thinking a bearing too but who knows. They were thinking a cracked differential but how could it not make noise with the 3.55s and as soon as the 4.10's went it, it happened?

 

[Mahstang]

Sounds like a helicopter. I just swapped out my 3.55s for 4.10s. Before the swap I had a rotational humming sort of sound coming from the rear end. I had the shop change my carrier bearings while doing the gear install and the noise went away. I can't tell what your noise is though...it seriously just sounds like a helicopter to me...

 

[CMK720]

Someone please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[CMK720]

Bump

 

[svtadam27]

Do you know what the fluid looked, and the condition of the other gear set? It sounds just like a pinion that's worn, or pinion bearing, could be the housing is messed up where the races go.

Do you have any pictures of the old parts?

 

[GT Speeder13]

did u have them install a bearing kit when the gears were put in? From what Ive heard, the bearings should be replaced to prevent noise...

 

[Viperbluelx]

The bearings don't need to be replaced unless they are high mileage or show signs of wear.
