Front Drive Shaft Update

[Dokatd]

Did you cut a stock unused boot as a baseline? The material at the bend may be deliberately thinner to prevent the outer edge stretching to begin with.

I have measured the stock boot. It does not thin out. The damaged boot ends up with completely new features in it at the end of the day. Meaning the boot is completely reshaped until it fails.

An yet every day, week, month and model year IA continues to build the Grenadier with the same inherent flaw impacting even stock vehicles as the miles increase. They have no intention of fixing this issue at all and if they ever officially acknowledge the problem it will be a forward production model only fix. At which point they’ll damage the resell values of all previously produced vehicles with the flaw.

Not a very good way to maintain customer loyalty to continue to produce vehicles with a ticking time-bomb of a problem especially if it ends up hurting someone with a high speed failure causing an accident.

Facts, lets just hope they don't change much so when that new model hits with a fixed shaft, all my aftermarket crap can bolt on.... lol

The takeaway is that the OEM front shocks allow just enough droop so that the boot comes into light contact with the surrounding metal housing/flange. Not enough contact to immediately destroy the boot but enough that over time the boot is thinned out until eventually it fails once the rubber has become too thin.

So, this also means that every time I put my truck on the 2 post lift I inevitably add damage to the boot?

You are not moving so I don’t see how much damage that can cause.

Good point you will be pinching the boot no matter what.

Yes, though it's minor. The damage is cumulative. You aren't killing it, but you are contributing for sure. The damage honestly requires rotation of the shaft to really cause damage.

Single point pinching? Every time at another point of the boot?

So what is more damaging to the CV boot, extended length shocks that allow for more droop thus more compression against the boot flange or continuous running at a higher CV angle if lift springs have been installed? Installing both longer shocks and lift springs would seem to guaranty boot failure. So if you cannot do both is it better to install taller springs for more ground clearance or to use longer shocks for more suspension travel. Given the mechanism of boot failure, taller springs are likely the better choice.

What about the opposite? Would shorter than OEM Shocks, such as those from Fox (listed earlier in this tread), act as ‘limiting straps’, and thus help avoid the ‘pinching’ effect in the first place?

Installing taller springs guarantees you are closer to the limit every time your suspension cycles. Hope that makes sense.

Yes, 100%. You will be slightly better off with shorter than stock shocks lifted or not.

The (CV) boot flange always looked out of place to me. It should bell-shaped like the end of a trumpet, or shortened.
