Using JB Weld to (temporarily) re-attach a snapped CV drive axle (your thoughts?)

[AZjeff]

Wouldn't locking the axle solve the problem?

That sounds right but how would you do it? Couple of big vice grips?

sleeving it and drilling holes to put bolts through both parts may work.

Good idea but set screws would be easier than drilling the axle under the car. So all OP has to do is turn a sleeve on his home lathe and drill and tap enough set screw holes to keep it together to the dealer. Piece of cake.

How far is the car from the dealer? Could you go old school and have someone tow you slowly with a tow strap? Under the present conditions nobody would probably notice.

Actually, could this work if it's REINFORCED with steel clamps??
Again, the trip to the Honda dealership is only 1.5 miles away.. creeping very slowly

Might be worth a try? Perhaps I can test initially by gently going forward and reverse and then braking with some power.

Remember: the CV axle snapped as I was BRAKING.

Id abandon any idea that JB weld is a solution.

Call the dealer and get them to get it towed. Surely they have a relationship with a tow company.

observe the angle of the breakage, u think if i JB Weld this, it would hold for 1.5 miles at 5mph ???

No, i don't think you understand the forces involved here.

Won't work. Years ago I had pump on a small electric pressure washer crack and I got the same idea. Started leaking as soon as it built pressure. Nothing but a waste of time/money.

If I were to do this: here's how I can test if JB WELD can handle some degree of torque.

1. set the parking brake.
2. put the car in drive, then put it in reverse.
3. still good? now add some torque but not too much to snap the axle again.

If it's able to handle a small degree of torque, I might be able to slowly drive 1.3 miles.

It'll snap as soon as you put it in drive. What did the dealer say when you called them and requested a tow?

JB weld, if applied to properly prepped surfaces, and parts A and B ratios are exact 50/50 by volume (dang difficult to achieve) is incredible stuff,
but,
It would be a waste of JB weld, and time, to attempt to join an axleshaft with JB weld.

Even if you were to have that on a workbench, and completely de-grease it, and form sharp mechanical tooth with deep sharp chosshatched scratches, and built it up thick around the break, clamped it perfectly and let it cure absolutely stress free, for 48 hours, it would fail the second it was put into drive, if it even stayed together for the reassembly process.

Try cutting a 3/8 inch extension on an angle and JB welding it back together.
It would likely break, torquing a 3/8" nut to 15 lb/ft.

That sounds right but how would you do it? Couple of big vice grips?

If I absolutely had to move...
Vise grips, fat screwdriver through u-joint space, or pipe wrench pounded on, and any well taped at the other end to a frame piece. Something long enough to lever the torque.
Think through the direction of torque.

Nope, I don't think it would hold for 1.5" to be honest.

^this is a pipe coupler..

Were I to do this:

I would fill this coupler with JB Weld, then use this to encase the repair (for extra re-enforcement)

Good luck. I'd bite the bullet and have it towed. Odds are Honda is going to pay, and you'll get the job done faster.

 

[joekingcorvette]

Just have it towed in to the repair shop it's your best choice.

 

[DuckRyder]

Purely as a mental exercise, how do you intend to get that pipe coupler inside the boot?

The boot has to be removed, I believe I can just pull it out with a little bit of force, otherwise I'll have to cut it.

That boot is a harmonic balancer, which most Honda's come with (for perhaps disputed reasons, aftermarket CV axles dont have this balancer unit.)

Basically.. it's unavailable.

The situation may have eaesd in the next few days though, as more cars are removed over time from the road and the tow trucks become available again.

Yes, the tow strap is that other idea I am strongly considering: with some care and the help of a friend, it might work.
