Rear Diff Help

[WYO_LGT05]

I have an 05 LGT is there anyway to make a stronger rear diff? Mine is busted and subaru has a complete rear diff for a lil over $700. Is there any way to do this cheaper? or is there a stronger rear diff that i can buy for launching?

maybe try rallispec

[WYO_LGT05]

Just checked out rallispec. it says... R160 rear LSD case requires modification when fitting with 3.545 and sometimes 3.700 and 3.900 final drives.

what is this modification?

You would want to keep your final drive. it has to match your front diff anyways. if you want a helical rear LSD , then you will just buy the carrier unit and swap you stock ring and pinion on to it.

Opie has a 5EAT, just for reference.

 

WYO_LGT05, I never asked you, in what manner did the rear diff grenade, exactly? You usually hear about center diffs crapping out on the 5EATs as far as I can tell.

im not sure, it just started one day. im guessing its from launches but not to sure. i was told by another member that had the same issues that it was the rear diff. so im taking it that thats the problem. unless anyone thinks its something else??

[WYO_LGT05]

its still drivable btw

[whitetiger]

sounds like you arent sure its busted. tesll us why you think its the diff. what are you experiancing?

[WYO_LGT05]

Every time i take a corner while acceleration i hear a repeated poping noise from the rear driver side. also if launching i hear the same noise.http://legacygt.com/forums/../images/smilies/confused.gif this does not happen at higher speeds, only from a beginning roll on turns and launches.

Doesn't sound good, I'd take it easy until you can have someone look at it. I'd hate to hear that the diff grenaded altogether. It could very well be the center differential, or a mount? Have it looked at either way. Easier said than done, it's a laborious project from what I know and rather spendy so I wish you luck and let us know what it turned out being.

[WYO_LGT05]

yeah im taking it very easy, i think im just going to fork out some bucks to have subaru inspect it.

[whitetiger]

you sure its not the rear end growl thats common on stage 2 cars? it kinda sound like repeated popping from the diff bottoming out the busshings on the case.

[WYO_LGT05]

if thats the issue how would i know? i there a walk through on taking the diff apart to check for this? or should i have subi do it for labor costs

[whitetiger]

why not have someone give you a second opinion by having them hear the noise first hand.

From the OP's description, that's exactly what I thought. Mine does the same thing.

[WYO_LGT05]

so if this is a bushing problem, what bushings do you think they could be and where to buy new ones?

[WYO_LGT05]

ok so i talked to a relative thats a mechanic and he believes i just need to grease up the cv joints as they get dry sometimes. so im going to purchase a needle oil gun and juice it up and ill let everyone know the outcome

[SBT]

^^ That's not going to do anything for the issue that you're describing. If the CV boots aren't compromised, then the CV joints aren't "dry".

[WYO_LGT05]

lol so what the hell is it, it cant be busted diff, changed fluid and no metal or signs of break. bushings maybe but have no knowledge on bushings

Look into this
