my rear D2 coilover seem to be seized and wont let me lower them, i’m assuming this is from sitting over the winter. any ideas of how to free it? besides using vice grips and ruining the threads on the inner body?
here’s a picture of the seized section:
Soak them in penetrating fluid for a day, are you doing this while the suspension is in or out of the car.
Where about in Flamborough are you? I work on my 240 at my parents place on the 8th Concession.
i tried doing it out of the car. i spray soaked them with penetrating oil, but didn’t actually let them soak in a bath of it. i kind of need them to be on my car so i can drive it to work and back.
i live on the corner of hwy 6 and the 6th concession, right where the oasis restaurant used to be.
i’m assuming you’ve tried this but if you haven’t bottomed out the lower sleeve on height adjustment, lock the two lower spring collars together as tight as you can and using a hammer and your spanner wrench, tap the spanner wrench CW (as viewed from top) on the upper collar of the two bottom spring collars. if it’s not that badly seized then you might be able to break it loose if you lubed it enough previously.
worst case scenario - weld something onto the lower sleeve so you have two parallel edges. mount the sleeve with the two edges into a bench vise, lock the two lower spring collars together, and hammer tap the aforementioned collar in the CW direction using lots of lube for the job prior to and during.
the most worst case scenario - you’ll have to cut that sleeve vertically for the portion that is threaded. i torched the sleeve to make the slit, being really careful not to let the shock body be exposed to too much heat. i then welded 2 pairs of mini clevises (basically 4 little nugs of steel), with 2 on each side of the cut slit. i then bored holes through the two pairs of nugs and tapped a convenient thread pitch on one side. then pick up the right bolts and washers and thread them in to form an alternative clamping system for the lower sleeve…this is similar to how some bike shock sleeves work.
i’ve been running that this whole summer and have had 0 issues with it. if you have to go this route too (if ordering an extra sleeve costs more than re-working) then just remember to be careful when loosening those sleeve bolts with the whole assembly on the car.
