I have Thule Hullavator Pro kayak racks and wanted to know how to fit and remove safely ?

Question edited for clarity, full 'make model (what it is)'.

retire it

Should have a electric motor that opens and closes doors to control flow to where you want it to go.

have a tranny service with flush done on it with fresh filter, fluid etc

Have you tried an upholstery or automotive upholstery shop? They should have the equipment, supplies and experience needed to fix something like this.

Hullivator lift cylinders are pneumatic, there is no fluid to leak. However, they do fail, and when they do, they do not provide lift. Despite what Thule says, the cylinders can be replaced. I have replaced 4 of them. Drill out the rivets holding the old cylinders in place. I bought new cylinders from LiftSupportDepot.com - they were very helpful and they charged a little less than $30 each for the cylinders. The first cylinders were 75 pound lifts. Those my sister found too light to provide all the lift she wanted. I have since installed 150 pound lifts (this will require a clamp). I cut off, and reused, the longer of the original Thule rivets where the shorter rivet formerly was, and used a 5/16ths 4" stainless bolt in place of the longer rivet. It will take a couple of tries and some prying to get all the holes lined up for that last bolt, under pressure, but in retrospect it will all seem to have been surprisingly easy. Good luck.

Hi,

This is Thule's instructions site. Just search for the model and it should all be there..

i get this with a bike rack....
its just the wind hitting it

Probably a fiberglass repair kit, available at most hardware stores. Let it cure longer than required prior to sanding. Then paint as required.
