We tried to strip down my hub today, to get the turrets measured up,as we are going to make a batch for members doing swivel hub refurbs. Unfortunatly we simple couldnt get the damn driveshaft out!.We tried the usual way with force..wouldnt budge. So tried a hub puller ,wound up as far as we dare without snapping the arms..still wouldnt budge a mm! So no fkn go!...We thought about heating up the hub..but being alluminium..not sure how that will effect it....possible just using a heat gun,instead of torch. Any ideas from you guys? I have heard of people needing new hubs when the bloody shafts wont budge. Bloody massive inconvenience,as we are no futher forward after a whole afternoons work!
well we have to get the inserts out to see if the material used is hardened steel..then we will know what sort of cost we are looking at. How do you buy them from mick?..might buy a couple from him to speed up the process of having the measure everything
I am very surprised the potential for a very large bill when changing the swivel bearings hasnt been covered before on here. If i cant get either driveshaft out of the hub,you will be looking at 2 new hubs,and 2 new driveshafts! Certainly no change from a grand! I see KTEC dont even try to rebuild the hubs..they just replace them. spoke to my renault tech mate today..he said last time he tried to get a shaft out of a R26..It actually snapped the hub,as it was loaded up so much on the hub puller..shaft didnt budge. He thinks,its the high torque of mapped cars,actually twisting the splines of the shaft in the hub.
Or poor previous maintenance on it. Can't say I've ever had any issues getting shafts out of mine, they were out a few weeks back after 95k and well over 300lbsft for most of that
its more like not enough use...i have had it virtually from new,and only do 3k a year. So the swivel bearing have just gone after nearly 10 years.. It has never wanted for anything on the maintenance front
my mates are engineers..will see if they can knock one of these up.We have a hub puller,but we had it wound up so much,we were afraid the `fingers` would snap.
That'll just fold the head over, ask me how I know. I bought this: https://www.machinemart.co.uk/p/cht464-front-hub-puller/ RS 175 Cup Lux
Come to think of it, when I did mine, even with the press I loaded it up and left it whilst I had a brew and a dump. Thought about heat, rejected the torch but did use the heatgun. Don't think that did anything. I also squirted some plusgas into it and let it dwell. Anyhow. After said brew and ablutions I returned for another go. Used the breaker bar on the press head. What had been substantial effort was now easier. It had crept! With that it just slipped out. Got a buddy who once worked for Renault. He reckons the factory use thread lock on the splines.

So I did my other side today. Had the same issue as you with the driveshaft: Much effort and careful wrenching plus the only penetrant I had (GT85), it came off. As suspected. Bearing was goosed: RS 175 Cup Lux
That'll do it! Took me about an hour. I know I know that sounds soft but I didn't want to damage the actual wheel hub bearing. Little bit at a time, some peno oil and let it creep then back to it. I also noted sole deformation in the press first. At the end with the single bolt hole. Got to make sure all wheel bolts are in equally so the press sits square. Once the deformation was maxed out then the real work of shifting the shaft began. I was going to give up then I noticed one less exposed thread than before. So kept at it. It needed maximum effort all the way out though until the very last few mm. Also my impact fun wouldn't move it so had to use the bar and my spindly arms! RS 175 Cup Lux
