Ram seals & stretched cables: the crooked, hesitant fold
Mechanical-looking · two causesHow it shows up
The top folds slightly skewed, pauses partway like it's lost its nerve, or sits unevenly on the rear deck when stowed. Sometimes there's a tide-mark of hydraulic fluid in the stowage area; sometimes nothing visible at all. Here's the catch: weeping ram seals and stretched cables produce almost the same symptom from the driver's seat — a roof that no longer moves square — and they need completely different repairs.
Why it gets misread
Guess wrong and you pay twice. We meet TTs that have had cylinders replaced when the cables were the problem, and cables tensioned when a ram was quietly bleeding pressure the whole time. A generalist sees one of these roofs a year and has to guess; topping up the fluid, the forum favourite, just masks a weeping seal while the imbalance keeps loading the fabric and guides unevenly.
How we sort it
Measurement instead of guesswork: we pressure-test the hydraulic circuit to see whether a cylinder is bleeding down, and physically inspect the cables, guides and pivots for stretch and wear. Whichever is at fault, we repair that — rams rebuilt with new seals where appropriate (see our ram rebuild guide), cables and guides replaced with OEM or premium aftermarket parts — then the roof is cycle-tested until it folds square.
