Guest Posted November 20, 2008 Share Posted November 20, 2008 Since I'll be pulling the engine it's a great opportunity for the 6-speed swap I was planning for spring. The swap involves swapping rear diff and rear axles. While I am there I'll be also putting SpecB aluminum trailing arms, which involves removing the wheel bearing hub from the arm. Did anyone remove these? Any tips? Subaru calls for a special axle puller tool, which I am not interested in buying. Any less sophisticated methods of removing the axle form the hub but better than BFH? How about removing the hub? Does it sit tight in the arm? Perhaps I should consider getting new bearings, but mine are fine at 44k miles, plus Subaru extended warranty on them so it's kinda waste to junk them.

MOMSWGN Posted November 20, 2008 Share Posted November 20, 2008 I'll be taking mine to the dealership to get the AVO CAB pressed in and installed. Too much drama putting those in. Link to comment Share on other sites More sharing options...
Guest Posted November 20, 2008 Share Posted November 20, 2008 AVO CAB? I think you're talking about *front* lower control arm bushing. Taking front control arms off is actually uber easy. Bushings replacement need press though, it's handy to have replacement arms ready. I am going to change rear arms, diff and axles... Link to comment Share on other sites More sharing options...
MOMSWGN Posted November 20, 2008 Share Posted November 20, 2008 I'm doing both (front and rear) at the dealer. Will throw on the coilovers and sways myself prior though. Link to comment Share on other sites More sharing options...
Underdog Posted November 20, 2008 Share Posted November 20, 2008 When I was contemplating doing this I found a few helpful hints: 1. You will need to replace the 4 (per side) Grade 8 or 10 bolts that secure the hub to the arm, with slightly shorter bolts because the arm is thinner at that location than the steel units. I will see if I can dig up the thread, pitch, and length. 2. You must be careful removing the hub units, so unlock the axle nut, loosen the 4 bolts slightly. Use a dead-blow or rubber mallet and hit the heads of the bolt to push it off the axle. 3. You can rent the axle puller tool from any Autozone/PepBoys/VIP with a deposit that is 100% refundable when you return the tool.

Guest Posted November 20, 2008 Share Posted November 20, 2008 Yeah, I remember tip #1 from your pm. Already ordered proper SpecB bolts. Thanks for other tips. Link to comment Share on other sites More sharing options...
Buru Posted November 20, 2008 Share Posted November 20, 2008 So you are going from a R160 rear to a R180? Spec b's have the R180 correct? I have been doing a lot of thinking to get the rear hubs form an 08 sti to fit on our Spec B's. Does anyone make race hubs for the LGT? If so then there would be no reason besides wheels to go to the 5x114. Thoughts. Link to comment Share on other sites More sharing options...
Guest Posted November 20, 2008 Share Posted November 20, 2008 Yup, I am installing R180 out of 06 STI with SpecB axles. 07+ SpecB has R180 with Torsen LSD (so does 07+ STI). Pre-07 STI has clutch LSD. Link to comment Share on other sites More sharing options...
Buru Posted November 20, 2008 Share Posted November 20, 2008 what is the difference between the Torsen LSD and a LSD? (nothing?) Are the 06sti half shaves same lenght but different end on it to fit the sti hub? I might try to go 5x114 all the way around using my current al spec b trailing arms. My major question is hub stick out distances? Link to comment Share on other sites More sharing options...
Guest Posted November 20, 2008 Share Posted November 20, 2008 I don't think WRX STI axles are same length but I don't know for sure. I am using SpecB axels. All helical (Torsen is one implmentation) LSDs, clutch LSDs and viscous LSDs work on quite different principle. Lots of info on the net. Link to comment Share on other sites More sharing options...
camber Posted November 20, 2008 Share Posted November 20, 2008 Hmmmmm....... Would the 08+ STI axles be similar length? Since the Impreza is based off the our BL/BP Legacy. Link to comment Share on other sites More sharing options...
Guest Posted November 20, 2008 Share Posted November 20, 2008 Possible, again hard to tell without measuring them off the car. I am also curious about 5x114.5 hub swap from 08 sti. Front would almost certainly bolt on, rear might be a problem. Btw, even if they fit, a potential issue is the hub compatibility with our ABS sensor/ABS module. But then a race prepped LGT could do without ABS anyway.... Link to comment Share on other sites More sharing options...
Buru Posted November 20, 2008 Share Posted November 20, 2008 truedat. I am slowly working on that new hub Link to comment Share on other sites More sharing options...
Buru Posted November 20, 2008 Share Posted November 20, 2008 If we could buy some of these parts to measure that would help out alot i need the dim of the sti new hub and the lgt hub!!! I got a theory Link to comment Share on other sites More sharing options...
Buru Posted November 20, 2008 Share Posted November 20, 2008 Which LSD is the best for track and witch for DD? Link to comment Share on other sites More sharing options...
camber Posted November 20, 2008 Share Posted November 20, 2008 Most would say HLSD for DD and clutch type for track. Link to comment Share on other sites More sharing options...
Guest Posted November 20, 2008 Share Posted November 20, 2008 Well, clutch type is not bad for DD - it's arguably better in really bad conditions like ice than helical (so is VLSD). Torsen works as an open diff if one wheel has no traction, like on ice. Link to comment Share on other sites More sharing options...
camber Posted November 20, 2008 Share Posted November 20, 2008 I was thinking more of the maintenance and noise issue. Also, some people find driving a 2 way tricky. Link to comment Share on other sites More sharing options...
Buru Posted November 20, 2008 Share Posted November 20, 2008 So Torsion is the worst and the spec b has 3 of them arrg How much are these clutch still LSD's? Link to comment Share on other sites More sharing options...
Underdog Posted November 20, 2008 Share Posted November 20, 2008 So Torsion is the worst and the spec b has 3 of them arrg How much are these clutch still LSD's? The Spec.B only has one Torsen diff (rear), and a viscous coupling center diff. The front diff is open on all Legacies, that I'm aware of. Torsen is only "worse" than VC or clutch when one wheel has very low traction (ice or if you are autox-ing and the inside wheel lifts)... If you can keep the wheels on the ground, the Torsen will react faster than VC or clutch. The Crimson Dynamo Link to comment Share on other sites More sharing options...
camber Posted November 20, 2008 Share Posted November 20, 2008 Torsen isn't the worst(it's jsut different) and the spec. B only has 1. The only real drawbacks of Torsen is that it acts as an open differential, if one wheel doesn't have traction and its heavier then a clutch type. Clutch type LSD need to be adjusted all time to get the maximum performance and action isn't instaneous like Torsen. However, because of their adjustability you can do some interesting things and they provide lock even if one wheel loses traction. Quaife is a good place to start to lean about HLSD http://www.quaife.co.uk/What-is-a-Quaife-ATB-differential BTW - there are different version of "torsen" type differentials but basic operation remaisn the same.

Buru Posted November 20, 2008 Share Posted November 20, 2008 Therefore for a 2008 Spec B the only real benifit would be to change the front dif to a ... VLSD Didn't sirmim do that (sp?) Link to comment Share on other sites More sharing options...
