Sorry maybe not the reply you are hoping for but I'm interested in how differently the car drives with the new box fitted.

 

@teflonbilly very.

Obviously only having it done today, and it's very wet here I haven't done much testing with it but it's very different. But with my torquey map its still an animal, possibly more so when I ask for too much

 

If the diff gears are shot, fitting an LSD won't help as it's only the centre, not the gears themselves. The LSD bolts to the large crownwheel.

IMO the diff gear will be ok (they're very tough) and the bearings are likely worn causing lateral play which will allow the crownwheel to move to the side. This would manifest as backlash as the pinion can't move side to side but you also get backlash from the driveshaft joints.

A set of diff bearings may be all it needs and you would do that when fitting the LSD to the crownwheel, although the pinion bearing may also be worn and contribute to the backlash as the pinion could move in and out a little.

Without an LSD the load is carried unevenly on the diff bearings. Fit the LSD and because it proportions torque much more evenly, spreads the load and thus wear. The LSD is actually good for the box and increases it's torque capacity. Also good for reducing driveshaft wear for the same reasons.

 

A LSD makes quite a big difference to the way a ST225 drives.

It is the biggest difference between a ST and RS when it come to handling.

I would say about 50% of the difference Nigel.

The RS has a much wider track, taller overall gearing through larger tyres, Revoknuckle (not massively better though), plus the more graceful spool up and overall engine response. There's a lot of difference over the ST.

I would guesstimate I've probably grabbed about 90% of what the RS has even with all my mods but it's still not an RS.

 

Didn't want this in technical... Less people likely to see it... Ah well

 

It turned into a technical discussion so it is in the correct location Michael, but if the talk goes back to selling, it will have to be closed anyway.

Sales are done in the classifieds, not in the main forum.

@Alb,

**Edited**

Nothing to see here....reread op, as usual got the wrong end of the stick!!

If your intentions are altruistic, that does put it in a different category.

No problem with keeping it in the main forum under those circumstances. :thumbsup:

 

For all the information, I bought a gearbox for £35. The diff and the refurbishment I've done are what I would have done to my box if it was opened up at 135k miles anyway. Night have cost a bit more to get the box I bought cleaned up as well but saved me worrying what I might find.

I cannot be bothered with trying to sell on eBay. If someone wants to make a donation for it it would be appreciated but if it can be useful rather than scrapped.

If no one bites on here I'll ask the gear box specialist if it's any use to them and if not I'll probably crack it open have a look at my self, add the gears to my man tin maybe and scrap the rest.

So before that happens, any interest? Lol

 

Very generous of you, especially as I am aware how much the refurb box cost you!

Can this be moved Alb, so everyone can see it, just another example of why this forum is better than most.

Kudos to you Mike.

My comments are about the handling and what is the biggest (not only) difference between the two cars!
