I recently had some used ford racing 4:10 gears installed. When I make a right turn I hear a rubbing/grinding noise pretty bad. It only does it when Im off the gas when turning. When Im on the gas it dont really do it as bad. Any thoughts on what it could be. I checked up under my car and I dont see anything that may be rubbing my tires. :helpsmili

 

Hmm that's wierd haven't heard of anything like that just while you're turning...Wish I could help, maybe bearings went bad or something? But that's just a guess. If it were your gears though you would hear them driving straight usually while slowing down, not just turning...

 

i say take it back to the people who installed them

 

I agree, but now that he got my money he seems a lil too busy to look at it. When I had 373s I didnt have that problem. Oh well, thanks.

 

I would make him find time or you can just go tell everyone how much of a crappy job he does.

 

exactly.. you paid to have 4.10s installed and working properly, not for them to make some crazy noises when you turn..

 

maybe they threw a spool in there too..

seriously though, take it back yesterday. dont let them tell you they wont fix it.

 

I had that exact same problem, it ended up being the carrier was messed up.I would bet that is your problem also.

 

What exactly is the carrier? So if that is the problem would I need to get new gears?

 

Did they put the correct gear additive in there? Motorcraft XL-3 is required.

 

The carrier(also known as the spool)is what the axles connect to inside the rear end(if I'm not 100% correct on this then someone please chime in)With my problem I had upgraded to 31 spline axles and carrier and it was bad from the factory,but mine made the exact same noise and it was only when i was turning, but you shouldn't have to replace the gears, unless you have been driving around a while like that, it is possible to have done some damage.

 

I dont think the he used motorcraft additive. How much would a carrier cost me?

 

My FMS was $200 for 31 spline

 

I still have my stock axles in. If that were my problem could I just replace the spool itself? Sounds like the noise is commin from the left side when turnin right. Makes not even wanna drive it. But thats my baby though. Gotta get her fixed!

Is that what I would need?

 

It says it replaces the spider gears which is what was screwed up on mine, so that may solve your problem, but i suggest having the gears removed and looking at everything before buying something that you might not need.It is possible that the gears are not set right, have the shop that did the work take on the responsibilty to fix it, they didn't do it right the first time.
