Hello Formites

I have a sticky problem with my hilux, the nuts connecting outer drive shaft to front diff. The rubber boots have split and so I need to remove drive shaft.....6 nuts/bolts, retainer clip and out comes the drive shaft. BUT, attemps to undo these bolts have failed. I have undone only 2 ( 6 each side) using pipe over socket handle (extreme force applied) but failed to make any movement on the other 4. I have borrowed a compressor and rattle gun also, still no success. :( Any tips for tight nuts or can I replace the rubbers by removing disc etc and dismantling drive shaft??????:)

Thanks in advance for any replies

Wisey, I am NOT familiar with the Hi Lux.

If you've been using a levered wrench, and rattle gun, then nuts are seized. I don't think penetrene sp or the like will help.

Are you able to apply some heat to the nuts? Say dull red, let get real cold again and try with a socket?

Sounds like a job for an angle grinder with a 1.0 mm. cutting disc. Cut across the nut, including the bolt, and knock out with a hammer. New bolts.

Hopefully someone more informed will have a suggestion more fitting, as mine is a sort of last resort thing.........sorry mate.

Gday Wisey,I'd go for heat.I know what you mean about them being tight,I replaced some seals in the front diff last year and struggled to get them undone,carnt remember wether their nylocs or not(not that it will matter after you use gas) but use some loctite on the new/used bolts,dont want them coming undone.

Have had the same with my forerunner.The bolts are like wheel studs they are fixed to the flange of the inner axle,so to undo, just turn the nut not the bolt.

I don't know my way around the Hi-Lux, but what size are these bolts? What diameter is the thread stud? With a pipe on a socket bar you can snap a high tensile bolt up to about 20mm diameter quite easily. They must be big buggers if you haven't snapped 'em already.

If you use heat, make sure you get 'em undone before they cool. The steel nut will shrink to smaller than it's original diameter when it's cooled and that makes it even tighter. Get it off while it's hot.

Good thing you added the extra bit on the heading, about Tight Nuts!!!

We had this problem last year, and didn't need the Gas Axe. Put the venicle up on jack stands, as high as practicable, and SAFE, and use a long ring spanner on easily accessed nuts. Turn driveshaft to access each nut.

Hit the end of ring spanner with heavy hammer, this should jar the nuts enough to release them. Piece of pipe over the ringey will work too. Ringey are closer to line of nut, whereas a socket setup is too offset.

You have to replace the entire d'shaft as a unit, either new or aftermaket rebuilt. The latter is the cheaper option.

Good luck, pr*ck of a job...

Quik Reply and thanks to you all,
got the job done, drives well, no gas, no axe and no lube required. once I took off disk etc the drive shaft popped out from diff housing and I was able to replace buggered boots. And about my tight nuts, well I'm going to see a specialist;))))
