Stripped my torsion bar mount...
« on: February 14, 2010, 01:46:08 PM »

I had just gotten my swayaway torsion bars all set up and adjusted. On the way home I heard a bang and the whole drivers side suspension dropped to the bump stops.  Turns out the mount on the lower arm stripped out.  I have heard of this happening before but I can't remember where.  Is there a consensus on why this occurs?  My first two thoughts are either the torsion bar wasn't seated correctly which I doubt since the rear torsion bar adjustment bolt as well seated which "should" ensure everything is correct.  My second guess is too much tension on the torsion bar, which I also doubt.  I was using a regular length socket wrench to do the adjustments so I doubt I could have put enough tension on it to strip it.  The adjustment bolt wasn't bottomed out although I had just reindexed.  Oddly, the ride after reindexing was much more supple than before.  Perhaps that additional softness was my bracket slowly stripping itself.  FML.  bang head






So now what?  Should I use the swayaways again or might there be an inherent problem?  They were used but in good condition. 
it looks like a new bracket is about $51.00 bucks and I MIGHT be able to find one in a junk yard.  Not many Frontiers with good fronts out here.  Are the longer arms "lift versions" more robust or do they use the same stock torsion bar mount?

Crap.  I just looked and saw the lift kits have just upper arms, not lower.

My .02 says that you will need to replace the bars, too. I do r&d as well as field testing for an outdoor equipment company. When I fu a driveshaft or gearbox coupler(spline, load bearing like a torsion bar), I find that both need to be replaced. For instance, if I stripped out the gearbox side of a driveshaft on a trimmer... and only replaced the driveshaft... It would happen again in no time.

I got the bar cleaned up and there seems to be little or no damage.  I know I SHOULD replace it.  There is some discoloration where it stripped but the splines seem to be intact.  $200 dollars for new ones.  Crap.

I guess it's worth trying a new mount. I fear it will hapen again sooner than later though. Good luck.

I'll have to figure out my budget tonight I guess.  New bars would certainly make the process easier.

I had the same experience with my used SAW bars.  I used heat to release the stock bars from the rear anchors.  That was a bad idea followed by the same heartbreaking faliure that you had.

In your case, it was not fully seated, OR you used heat to remove the stock bar.

Solution:  Replace the anchor (or whatever they call that part.) and reuse the bar.
Make SURE the bar is fully seated in the new part.

Nope, no heat.  Came out nice and easy.  I'll call around tomorrow and locate an anchor.

It looks like it was only in halfway.  That is easy to do at the front. 
Replace that anchor and you will be back in action.

Guess I will just have to whack it harder.  Oh well.  Since these are used torsion bars will I be able to set them equally side to side since they have been used in another position before?  Does that even make sense?

Check your yahoo email.

They should work fine.  Don't get all superstitious.

We had a guy do the same thing to his pathy back at the NOAS Fall Run last year.....   seemed as if his torsion bars werent fully seated as stated previously in this thread....  we did a quick fix on the trail and seated them back in all the way but I'm not sure if they held up hehe

Same thing happened to me after putting my lift on. I'm sure it wasn't seated well. Went over a speed hump and *drop*
The Calmini bars were fine. Just picked up a new anchor at the dealer. Lesson learned
