Would a bad diff cause a car to pull right under load and left on decel? I mean going from 10% throttle to 0%. Not wot.

 

What is your setup? Open diff? LSD? Had a similar problem in the past but under more heavier throttle. Was a bad axle that was binding..kinda scary! Would pull to one side under throttle..then snap back in the opposite direction when I let off the throttle. Changed the axles and problem was solved.

 

An exploded clutch LSD that is only driving one wheel will do that, like my Kaaz did.

 

lsd, pulls strait under wot.

 

Do you have the clutch type with a possible issue like Bone stated? Any irregular noise? Other than that I would look at suspension condition/settings, or tire psi if you haven't checked those yet. Usually those would give you a pull under heavy throttle but, you never know! Especially strange since it doesn't pull under WOT.

 

Loose suspension bolt will cause that too.

 

Not a clutch type. New axles. Bushings and alignment are perfect. I'm going to throw it on the rack Fri to see if anything shifted. anyone else have weird issues with a diff?

 

Did it do the same thing before changing the axles? Well keep us posted on what you find Friday.

 

Yes. Different axles did the same thing.

 

Well the axles are ruled out...As far as the diff being bad, a bad helical diff is usually noisy and gets progressively worse. Keep us posted on what you find Friday

 

Will do. Thanks for your help.

 

NP anytime!

 

Car is strait as an arrow. Thinking its the diff. anything else you guys can think of.

 

What diff do you have??

 

Obx yo! I wanted.to try it and see. A buddy has had zero problems, I figured I would try it. With what said I'm thinking this thread is going to turn into a Obx sucks thread now.

 

Haha! I will bite my tongue on this one! LOL! Did you check all their obvious problems before installing the diff? Lose casing bolts, incorrect center washer installation, and incorrect specs on bearing spigot(differential bearing killers!).

 

Yep stripped it, replaced, cleaned, debured, new washers, and bolts. Are people having good luck with mfactory units?

 

For how cheap i got it I figured it was worth a try.

 

We have had excellent experiences with the M-Factory units and they have a lifetime warranty. They are really nice units! I also like the Wavetracs and the Quaife when the price is right. Waiting for a Wavetrac to get here for a customer on a turbo drag build.

 

We use MFactory LSDs in our builds. I have sold about 200 of them and never had a problem. I keep them in stock if you decide to go with one.

 

Pm me a price. Thanks!

 

well my pulling problem was the diff. the gear where the axle slides in, jammed to the diff housing on one side. 3lb hammer couldnt get it out.

getting a mfactory sometime this week.

 

Yeah they can be a bear to get out!!! I demand some pics! Good luck!

 

pics will be up when i get home... about 100 miles on the rtf and its FULL of metal. every gear in the obx looks beat to hell. i was throwing the housing on the ground to see if it would come out. nope. that **** is locked up in there.

 

Well good luck to yah!! Will be checking in for some pics!
