firevsfire Posted February 13, 2012 Report Share Posted February 13, 2012 I have a whiney diff in my 38 wagon, is it easy to replace the bearings, or should i get a new diff.. - Where would i get bearings, is it as easy as going to a spare parts store? - How would i pull apart my diff?

Jono.C Posted February 13, 2012 Report Share Posted February 13, 2012 You can't buy a "new diff" but you can buy a secondhand or reconditioned one with lower k's> If you have to ask how to pull a diff apart, i wouldn't do it. Send it to a mechanic to have it done, or pay someone from here maybe near you too put it together for you. If you can't afford to pull the diff out right now, you can get a tube of goo from autobarn which you put in you diff which is supposed to relieve friction a little and may help your diff last a little longer. But from what i've found with corolla diffs is they all seem to whine, so it might be fine anyway depending on how loud it is. Quote Link to comment Share on other sites More sharing options...
firevsfire Posted February 13, 2012 Author Report Share Posted February 13, 2012 So getting some fresh bearings is a viable option? Finding labour is easy, just don't know where i'd get some bearings from.. Quote Link to comment Share on other sites More sharing options...

altezzaclub Posted February 13, 2012 Report Share Posted February 13, 2012 ..and a lot of the whine may be the crownwheel/pinion setup, which is the hard part of doing one yourself. I was quoted $1000+ to rebuild a manual one we had that whined, so we've just stuck with the auto one. Quote Link to comment Share on other sites More sharing options...
JordyKE Posted February 14, 2012 Report Share Posted February 14, 2012 Had a whine in my diff that had gone on for about 6 months. Didn't get any better or any worse through that time, but caused alot of drag. I'd say just find a diff, which is pretty easy and take it to a specialist just for them to look over it if you don't really know what you're looking for (which could be a problem within the internals of the diff) And yeah i agree all rolla diffs seem to have a bit of a whine. Actually i should post a picture of what my diff had done. The pinion was rubbing back and forth onto the the housing of the spider gears. So much metal found haha.

ke70dave Posted February 14, 2012 Report Share Posted February 14, 2012 does the wine change depening on what direction you are turning? if its an axel bearing, when you load and unload the rear wheels (turning the car) the noise will change from either gone completely, or very very loud...and it will be independant of load on the driveline. if this is the case, axel bearings can be bought from anywhere, but you need a press to get them on and off the axel. best bet is to remove the axels, drive down to your local mechanic with bearings in hand, and get htem to swap them. if the whine is a constant whine, independant of driveline load, and independat of turning (load on wheels from turning), it will most likely be bearings in diff centre carrier, i belive you can DIY these. but ive never done it. and i think its a bit trickier with having to set shims etc. if howeever the whine is completely dependant on drive line load (ie shuts up between gear changes and load on the wheels (turning), then perhaps you are looking at problems with the diff gears themselvs, or possibly the pinion bearing. i have no experience here, i woudl be inclined to find another diff that hopefully was in better condition. diff gears are very expenisve (compared to a 2nd hand idff), thats if you can get them.

JJT036 Posted February 14, 2012 Report Share Posted February 14, 2012 Emergency option:: All else fails try some moreys Gear / diff oil until you find a replacement diff it will quieten it down a bit and give it a little longer life till you find another diff Quote Link to comment Share on other sites More sharing options...
firevsfire Posted February 15, 2012 Author Report Share Posted February 15, 2012 The whine just gets louder the faster the wheels are turning. I had some bearings priced up at Lonsdale and for a borg warner diff and for an import. The borg warner bearings are $89 and for the import they are $169.

TOM Posted February 15, 2012 Report Share Posted February 15, 2012 I remeber starting a similar thread when I owned this car - just never got around to fixing it haha! Sorry mate! I tried numerous times to get those axles out, and they were very tight. As others have mentioned it could be more than just bearings too, and as you've discovered bearings aren't all that cheap. Neither will the labor be to remove those axles - it will require heat and/or one big-ass puller. The other option is to swap the diff for one out of a sedan (cheap and readily available). The wagon has a 4.5:1 diff, where manual sedans use 4.1:1 and auto sedan 4.3:1. Thus the wagon diff gives more take-off / less top speed and the sedan diff gives less take off / more top speed. In my opinion this is great as the car will cruise at 100kph more comfortably and give you more legs in the gear and better fuel economy, and it's a straight swap over with no mods needed as far as I know. A 2nd hand KE55 diff will cost you $free - $100 and is the best option in my opinion, unless you are mad keen on keeping the short wagon gearing. Hows that clutch holding out? Hope she's been treating you well otherwise! Quote Link to comment Share on other sites More sharing options...
B.L.Z.BUB Posted February 15, 2012 Report Share Posted February 15, 2012 I though I had a whiny diff, turns out it was the missus. She's not allowed in my car any more. Quote Link to comment Share on other sites More sharing options...

Hope she's been treating you well otherwise! I remember you saying about the axels being pretty firmly in there. I'll probably just do as you said, it could use a bit more top end cruisiness. The clutch has been fine, loving it mate! :laff: Quote Link to comment Share on other sites More sharing options...
