I don't think Haynes is necessarily wrong, I have used it for many years although only recently for rear bearings. I have used more recent Haynes manuals (eg 940) and they are no-where near as comprehensive as the 300 series manual, and are noticeably smaller.

The torque is massive for these sorts of bearings, I can't even achieve the requirement for the 940 fronts (100Nm+45deg) with my normal tools (had to buy a breaker bar), they are known for breaking tools. What would happen with 60Nm I do not know, but it mght not pull the shaft through sufficiently to clamp the inner races together. If 245Nm (Haynes) does not do it I cannot imagine pressing will do any better. I have used 180Nm (highest setting i had) + what ever I could manage, seemed to work ok. My new Torque adapter only goes up to 200Nm, pah!

On inserting the bearing there is a risk of damage if too narrow a pusher is used, it should act only on the outer shell of the bearing and not push via the inner. I much prefer my temperature expansion method, no force or special tools are required.

I used an press but on the inner race however I only used the low pressure piston, I wouldnt want to use the high pressure piston

I pressed the stub axle in and torqued the nut to 245Nm which required significant effort

You really shouldn't press against the housing as the force is going via the balls, but the bearing is probably designed to take a big force sideways so you have gotten away with it assuming you've no problems. I am actually more worried about pushing the inner race out the other side and destroying the bearing cage, eg if the axle catches the 2nd race.

I pressed against the inner race, the bearing and housing where laid on top of the stub axle, and then pushed the inner race over the stubaxle

Matt, if you only torqued it to 66NM (only just saw your post) then that might suggest its not been pulled through properly for certain. The 66 refers to the half shaft bolts

Right well yesterday I had a go at tightening the damn thing. Accidentally managed to drop the car off the jack and axle stand (working on mud). Anyway This put the weight of the car through the nut so that should have tightened it a bit. As i had the driveshaft off that side, i turned the other wheel while in neutral. I got like a clunking clicking noise :/ Couldn't quite tell where from But i'm pretty sure its the diff or cv joints. Swapped the rear wheels round too. Drove it last night and it's worse.

Think I'm just going to find another whole gearbox and diff then either just fit that and give Atchi back the LSD assuming i've not buggered it or swap it into the new diff, using all that diffs parts to prevent mis-alignment of the CW/P. Then pay a garage to do the wheel bearing i seem to have fucked up. The LSD is amazing and well worth what i owe Atchi for it, the reason i'm contemplating getting rid of it is because i'd rather drive a car with an open diff confidently than drive a LSD'd car with noises and the worry that somethings going to break.

Could really do with a couple of weeks in a garage with a solid floor, working on the car to get it sorted. I have no garge, no solid floor and have to drive the car everyday till next monday and have no free time when I can work on the car.

So my shopping list is as folows:
360 gearbox + diff pref. GLT
4xCV joints
A garage to do me a wheel bearing

Fitted an Omex rev limiter and launch control which is pretty cool, I'll get some pics and a video if i can.

And I'm back to 18mpg, i don't flog it at all with it having all the problems, just drive as smoothly as possible. Saying that front wheels could be pointing anywhere as both radius arm mounts are buggered and make lovely cracking noises all the time.

Cheers,
Matt

right car's off the road, really not worth the hasstle of driving it. Gonna try and get a whole new gearbox + diff to stick on for now, see if it cures the noise as i'm not 100% its the wheel bearing. At the same time do the gearlinkages and radius arm mounts. If that's cured it i'll think about sticking the LSD into that casing and using the same bearings, CW etc so as to prevent mis-alignment and see what it's like. If it doesn't cure it I'll get 4 CV joints if they are still avail. and get the car up to a garage for the wheel bearing

CV joints are super easy to check dude, when they are off the car (halfshafts that is) grab the outers. There should be *no* movement on the rotation.

get some vids up of this rev lim and launch control :D

i know how you feel working on uneven ground, really gets you down at times as every thing takes twice aslong, try not give up

cheers, Think I'm getting a replacement diff and box from John So that will go on and at the same time check the driveshafts, after that i've got a radius arm mount to swap over after i re-enforce the one to go on so even if the middle goes the bush cup will stay on. I'll do the gearlinkages at the same time and lengthen the exhaust where it's hitting the heat sheild. Hopefully get the blowing sorted too. Then she's drivable again and if there are no knocking noises etc. then i've done the wheel bearing right and she can be given some stick.

After that i'll take the current LSD diff apart and see what's been making the noise, I'm thinking chipped crown wheel teeth due to the fact i never set the diff up with teh shims and used a bearing out a completely different diff on one end. As far as i can see, if i swap the LSD into this new diff I'll get, swapping both bearings, crownwheel etc. so all parts match the case except the LSD it's self then I shouldn't have problems?

I'll get a good video when i can. Still deciding between soft cut and hard cut, hard cut produced flames but could be pretty dangerous as you just loose all power :/ soft cut sounds mint and work the best with launch control but no flames. The boy racer in me says flames but think it will stay soft cut haha.

Little idea i had when i was stripping me old corsa down and after being in me mates corsa on coilies ... corsa coilies on a volvo strut. The coilovers are cheap to buy compared to what gets spent on getting them for our cars and i cant see it being overly complicated (nothing ever does when it's an idea). They are camber adjustable and simply bolt on. Corsa's must be a bit heavier at the front like. I have a spare volvo and corsa strut that owe me nothing, I also have a welder and grinder. For the pennies I'll spend it's worth a go.

Also going to get cracking with the LH2.4, gonna get quotes for the 60-2 trigger pattern machined into a crank pulley. Then the parts, off teh top of my head, I have to get are:
The EZK ignition ECU, the Air flow meter, the 2 relays, knock sensor, o2sensor, crank sensor, idle control valve, diagnostics port, a coil and a fuck load of plugs including the ECU ones and a load of wires with different colours and a few reels of insulation tape.

Aye its hard working in mud and that but I've found over the last week most of my 'mates' who happily get in my car when they need to get home or want a mcDonalds, seem rather less happy to give me a 5 minute lift home from college :/ So the cars getting fixed ASAP so i don't have to walk everywhere

Hi Matt

Any more info on this lauch control? how does it operate? cutting the spark?

It's an Omex rev limiter. And yes, cuts the spark, rather than the fuel like most factory fitted rev limiters. The launch control is just another rev limiter that you set lower and turn on and off with a button. The fuel still pumps round and is chucked into the exhaust where it ignites with the heat and can 'supposedly' be used as a cheap anti-lag kit as the burning fuel spins the turbo. on mine (with straight through exhaust) flames occasionally travel the length of the exhaust :D Dunno if you've ever done the 'key flick' thing? rev then turn ignition off and back on again? makes a bang if you have a straight through pipe.
You can set the rev limit anywhere between 1000 rpm and 20K rpm on the 4cyl setting and the same for the launch control. You can also et between hard cut (maybe 3/4 of a second between the ignition cutting and coming back in) or soft cut (where it starts cutting 'softly' 200rpm before the limit then turns on and off very fast to keep the revs constant at the limit). The launch control is used like holding the revs at say 3k before you set off the line. Normally when you set off you floor it and if the wheels spin the revs just shoot up and you have to back off to get traction or wait for the wheels to stop spinning - either could loose you time. With this you can hold it at say 3K to stop the wheels spinning. I don't do any motorsport but i wanted a rev limiter and a second hand one came up on ebay that had launch control anyways for cheap so got it. Plus its puts the saxo's at college to shame on the rev limiter competitions they seem to enjoy hahaha. Wiring wise its simple - an earth, a wire to coil + and a wire to coil - then there's a wire for the launch control switch. Think they are like £100 new

Here's a couple of vids i found off you tube

plans sound good, no matter what people say every one likes flames lol, dose it allow you to raise the factory rev limiter for when your driveing? found myself on the limiter a few times drifting, sounds good but cant imagen it being very good for the engine
