Bought my 06 Elise a month ago and I’ve learned a lot from this board. Just want to say thanks to everyone who stresses the seriousness of the rear toe links and the frequency which the nuts get loose.

I have 22k miles and probably just performed the first transmission fluid change, used MT-90. Everything went fine and I checked the rear toe links since I was there. The driver’s side wasn’t too bad, about a half turn loose from 39 ft-lbs. But the passenger side was scary. It had 5-10 ft-lbs on it and took 2.5 turns to get it right. :crazyeyes Would have been a mess if it let go. If you are new to Lotus, change the oil and check your toe links. :no:

Also installed the Sector 111 shifter brace and Stan’s mod. Shifting is must nicer. :coolnana:

You should probably replace the one that was very loose. With the torque that low, it was probably sliding and putting sheer stress on the bolt (stud), which it isn't designed to take. The bolt may be damaged, and could break at a later time.

You used the old torque setting. Lotus changed it to 44.25 ft.lbs. (60 Nm). You need to tighten them to this new setting.

Thanks for the update on the increased torque requirement. Mine were close the first time I checked them - not much more than half a turn to get 39 ft. lbs. They have remained tight each time I have checked on each oil change.

My experience with the toe link bolts/nuts (on two cars) is that the nuts will back off over time... until I put Nord-Lock washers between the nut and the subframe. I've done this on my Exige (with the Sector111 RTDBrace) and my 2-Eleven (with the factory track brace). In both cases, I've had no problem with the link bolts/nuts backing off after installing the Nord-Locks. I still check them before every track event though...

The problem with the nuts losing torque was tracked down to poor galvanizing, not the nuts backing off. There is a thread on it somewhere at this site. The galvanizing was uneven and was crushing slowly over time, thus letting off tension on the bolt. Hence, Lotus also changed the checking of the torque to every service interval instead of just the first one, in addition to increasing the torque value.

I also put on Nord-Lock washers pretty early, but the bolts would still lose some tension for about the next 3 service intervals after I put them on.

Thanks, do you know the part number for the bolt? And will I need an allignment after changing it or is the movement limited? I took a good close look at the nut and did not see any evidence of it sliding. The color and dirt around it was consistant. But it looks easy enough to replace. I'll increase the torque next time I am under there.

This is correct - it the toe-link ball joint / A-arm bolt was loose, then it is probably "stretched" and needs to be replaced before it fails.

Go to lotusgarage.com, and you can find the part number, and even order it. Or, you could splurge and upgrade your whole toe-link setup with kits from various vendors (Sector 111, Blackwatch Racing, some Australian company, others). If you use it with the standard tires (not racing tires), then you probably shouldn't upgrade the toelink. Better for it to break if you hit a curb than to bend the frame. On the track, it is a different story.

I don't think you have to redo the alignment if you make absolutely sure the link length doesn't change. However, if you have not had an alignment yet, I would recommend one. The factory alignments have been poor. My factory alignment from the factory was pretty far off in toe, and caused excessive tire wear.

when in doubt, change em out. These parts are flight critical. Yeah they could have just backed off or worked loose, but they could be stretched out and in the process of failing, you just can't tell without doing a lot of expensive analysis. You can replace the suspect parts with any number of factory or aftermarket replacements for less than your what your deductible would be if they were to fail while cruising the back roads (or worse, while being thrashed on track). Personally, I'd rather err on the safe side.

Yea, just had it replaced on the driver rear. That sh!t was scary when it happened on the pway. Very scary.

Also might check with Turbophil from BOE Fabrication. He has a set of toe links, though I don't think on his website. Put some on my car last year and still as tight when I checked em last weekend.
