Torsin key stripped

ori said:

Anyone ever heard of the splines stripping out on a torsin bar key? Truck is a 2001 Frontier 4wd CC with Calmini upper arms.:thatswck:

human error. thats about the only way

I've seen pictures of it happening. The T-bars weren't installed correctly. So yeah theoregonfront has it pegged. If it was sufficiently deep it would not strip. Got any pics of the torsion bars?

Lets see the picshas!!! I don't see why they cant strip.

It may be theoretically possible but you have about an inch of spline in the front and I think about another inch in the rear. I indexed my bars on the HB one time and I couldn't get enough bolt through to start the nut on the rear cross member. I don't think you can the combination right on bolt and index to put that kind of torque on the bar. It's kind of like breaking a rear end. It can happen not very often or likely.

A few guys on Ronin said it happens pretty often. The bars are installed correct.(never been out that I know of) they have about .5" of spline engagment at the key. I thought about pulling them back to get more spline in the key but then it pulls alot of spline out of the A-arm mount. I would like for the bars to be about .5" longer. I'm glad I wasn't going very fast when it happened. Scared the $%^$ outta me. Sounded like a gun went off in the cab. I guess I'm too hard on the truck.

it happens. people reindex them and crank 'em too much. its just springed steel with splines... if you over work any spring its going to heat up and fail. same as bending a paper clip over and over, if you overwork the metal, its going to heat up and fail.

No the bar itself is fine. It's the splines in the key that failed. The bars have been turned up but not reindexed. I think I'm just gonna go ahead and SAS I had talked myself outta that because it is my DD but I do take it off road and i'm pretty hard on it so I guess am just gonna go ahead and do it.

I have seen this before on a truck that had the t-bars swapped out, the owner did not get the anchor arms seated back on the ends of the t-bars correctly and when he went over a set of railroad track *POP* went the driver's side. Sucked for him but I had a spare anchor so he got his truck back together pretty quickly.
