Wrong hub and stub shafts? Sierra based suspension
Apologies in advance but I'm here as a complete novice and non-Ford owner, however would very much appreciate your expertise.
I have a MGB GT that has been heavily modified (MX5 engine + TD04 turbo etc etc), and currently have a ford based rear independent suspension sold by Hoyle Suspensions. The suspension comes with its own sub-frame, and houses a Ford 7.5" Granada 3.6 Quaife LSD, custom half shafts, that then go on to a custom alloy hub carrier. The only true Ford parts are the stub shafts - 108mm Lobro -, rear alloy hub carriers with their supplied bearings - sold by Amebo engineering- and standard brake calipers.
However, the issue I am presently having is that if I tighten up the stub shaft nut to the recommended 200lb/ft, everything seizes up and I just cannot move the wheel at all. To get the wheel to move it (using both hands) is for the nut to be barely tight with minimal torque, I mean minimal, something like 20-30lb/ft.
My question to you guys, is could I have bought the wrong stub shafts and hub carriers?
Spoke to Anembo Engineering and they have said they had a few bad batches of hub carriers with issues and asked for it to be returned to them so they can have a look.
Sent it back to Anembo and he very diligently fitted them up to his jig and found no issue with the bearings or carriers....what the hell is wrong with the suspension then?
Could the Quaife LSD have been rebuilt wrongly? Its fairly stiff to turn without the hub carriers as is, but I sort of thought that would happen with a LSD?
Just thought Id update this thread in case someone 10 yrs down the line has the same issue.
I havent yet confirmed if Im correct but it all points to simple stupidity on my part, Id read on different forums that the load spreader plates that sit on the CV joint and spread the load over the thin CV tin boot were pointless...and pointless as they may be, the bolts included with the new stub shafts assumed you were fitting the damn load spreader plates so they are too long without the plates. Once you start loading up the hub nut they bloody grip on to the inside hub.
Result is Ive got the inside of the hub being chaffed away by the 2-3mm oversized bolts. I must add that the hubs are aluminium and bolts 12.9HT, needless to say who won that battle. I dont think its an issue with the hubs having a little groove rubbed off on the inside as theres no matting surface affected, but it certainly is a learning point.
These spreader loads are quite hard to find but Ive managed to get some on eBay. Will update again once these arrive to see if theyve sorted the problem - shame it will be a long wait now with Christmas holidays.
One thing to watch is the after market metal CV boot carrier part that goes over the joint doesn't tend to have the same shape as the original Ford parts.
I bought some stainless load spreading washers and they wouldn't fit without a lot of work to make them clear the bumps that are there on pattern parts.
