removing arms from sierra diff
Hi Guys
i am having some real issues getting the Torx head screws that hold the pop in shafts to the diff.
i have tried bucket loads of WD40 and no movement at all, also have tried heat but only a little.
i am worried about rounding off the tops.
also having problems with the nut holding the rear hub to the drive shafts.
Cheers
Phil

They are a bugger to get off. You need a good quality torx drive. I used one from my local garage, and I was worried it would wring off. (It was a
snap on)
Other way is to cut the heads off with a 1mm slotting disc in an angle grinder. then replace the bolts with 12.9 grade Hex socket bolts... Much better
option and not that expensive.
I replaced mine with 12.9 grade hex socket head bolts.
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.

Treat the torx bolts as expendable.
The long winded messy way is to grind the heads off.
The quick way is to use a hammer and cold chisel to ge them started.
The big nut is best loosened before the axle is taken off the car and it's still on the ground.
Alternatively take it to your rlocal friendly garage who can take it off with an air gun.

There's also a very good product from Loctite that freezes bolts,
Much safer in a confined space and less likely to do any damage to other things and works on similar principles to heating things up.
I've used it very sucessfully in the past, and its available in Halfords and not excessively expencive either.

so long as the torx driver is of good quality you should be fine, if one does snap it's not a problem as their just long bolts and can be
replaced. They are though very tight so just keep at it, don't use heat use a bar on the end of your ratchet.
As for the hub, put the big nut back on but not fully, put a piece of wood over that and thump it with a bit hammer, it will move. Just don't
hit the bare threads. A three arm puller will also work here but I've never found the need for one.
hope this helps

I got through 4 impact Torx Drives before i resulted in 1mm cutting disc!
Using the disc is a doddle, they wind out by hand once the heads are off!

Cut the heads off and remove the drive shaft coupling then get the remaining stud out with grips. Replace with threadlocked Allen bolts for a few quid
and never have the problem again.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Bit late now, but get a can of PlusGas - better for taking things apart than WD40.
I managed to get mine undone with a torx bit.. but it was kind of spirally when I'd finished!
