7MT hydraulic accumulator failure

[tdhyden79]

I spent just under 3 weeks in the San Juans with the family enjoying all the trails. The day before we were supposed to head home, we jump in the Squatch and the clutch goes to the floor...and stays! I only have 40k miles on the rig with mainly commute driving and some occasional offroading. I pop the hood and find that the PLASTIC accumulator on the clutch hydraulic line has failed, separated, and drained a bunch of clutch/brake fluid all over the ground. Special order part only, takes at least a week to get in. I ain't got time for that! So one tube of JB plastic weld and a few feet of stainless wire later, I MacGyver the thing back together. It survived a 15 hour trip back home to DFW, TX.
Has anyone seen this happen? Would it be reasonable to replace the plastic piece with hard lines? Tick Performance makes an adapter for the ford QD lines, two of these and a 4an coupler and you should be good, right? As far as I could find, this part is just a "clutch pulsating damper" used to meet NVH requirements.

And, here are some pics of "Harry" on the trails!

Wow that's wild! Sorry I don't have anything to offer, subbing in case someone else does.

Keep us posted if you make a "permanent" non plastic fix. Glad that didn't happen on the trail.

Your fix is likely better than the plastic replacement. Nice MacGuyver there

I wonder if this a common failure for MT Broncos and if there is a better aftermarket solution.

Came here to say your solution will outlast anything the aftermarket comes up with. Nice work!

I’ve heard of a couple of master cylinders failing but this is the first I’ve heard of an
accumulator.

Granted I don’t work in a shop and most of my exposure is from around these forums

Well dang, I missed those others apparently. Guess I need to decide if I need to order one to keep with me on long trips, or find a way to delete it if it's really not needed..

Or maybe preemptively reinforce mine similar to what OP did.

Ah Ducati wins again - those were the threads I was remembering but i only recalled fhe titles I guezs

Same comments as above - great field repair. I've 60k on my 7MT, enough desert trail miles and Phoenix heat, and not had your experience. I'm going to remember your solution but rely on the idea that the failure was an outlier.

Dude, nice trail save! Kudos! Curious, how did you bleed it?
