DPS.01 Posted March 13, 2023 Share Posted March 13, 2023 @alchemist: it is not… it is a NOS GM part; hydraulic strut. … two things: 1. only have one 2. since it was mfg in 2004 and sitting on a shelf in NE since then, it is unknown if it is good. not sure how one would test a hydraulic strut @ home… 1 Link to comment Share on other sites More sharing options...
2seater Posted March 13, 2023 Share Posted March 13, 2023 I thought the struts were gas charged and will fully extend unless restrained?? Link to comment Share on other sites More sharing options...

Not the OEM ones, those were not gas charged from what I have read. The Monroe 71966 were gas charged. 1 Link to comment Share on other sites More sharing options...

2seater Posted March 13, 2023 Share Posted March 13, 2023 I tried to do that on my laptop but I couldn't get my Etch-a-Sketch brand representing three dimensions. Probably operator error.😖 Interesting about the OEM vs aftermarket, thanks. 2 Link to comment Share on other sites More sharing options...

The sleeve length will probably need to be adjusted based on final stack up. 1 1 Link to comment Share on other sites More sharing options...
alchemist Posted March 16, 2023 Share Posted March 16, 2023 The weld adapter for the gland nut came back at $50 to $75 each, depending on quantity ordered. Will wait to hear back from DPS.01 regarding the ability to internally thread the OEM housing before moving further. Still awaiting the 3D printed plastic concept samples and the pricing on the sleeve nut. 1 Link to comment Share on other sites More sharing options...
sarookha Posted March 16, 2023 Share Posted March 16, 2023 For what it's worth, I contacted Moog Suspension and filled out their "Suggest a part" form. https://www.suspension.com/suggestapart.asp?vehicle=8872 Completed the form for Reatta rear struts, and got back this helpful reply. "if you have friends or family that also need this part made or another one that is not listed, please have them fill out the same form. With enough input from our customers the factory can make a better decision on what products to create next." 2 Link to comment Share on other sites More sharing options...
DPS.01 Posted March 17, 2023 Share Posted March 17, 2023 (edited) Received the machined strut body today ! 👍 Worked out really well. Strut cartridge fits tight, secure, and aligned within the housing. Machined Strut Housing: KYB Cartridge Installed: Monroe Cartridge Installed Additional Info: * This was a proof of concept. * Thread size is 51 mm; 1.5 mm pitch * There is complete thread engagement for the KYB gland nut. The Monroe gland nut has more threads and does not have engagement of all threads. (approximately 2X the amount of threads than the KYB) * Have not yet torqued the gland nut to spec. (82 ft-lbs per Monroe) * Overall length of modified strut assembly is ~2.5” shorter than the OEM strut fully extended. * Will require extension of the upper threaded portion of the strut or the sleeve nut @ alchemist has out for quotation (preferred). * Should not require any other shimming or adapter to keep cartridge and housing in alignment with each other. * Previously posted information states KYB insert cartridge is not to have oil surrounding it. Monroe instructions state that ~50 cc of oil should be added to come 1/2 way up cartridge to aid in heat dissipation. Add or not… depending upon cartridges used? Overall very pleased with the outcome and collaboration on this project. Edited March 17, 2023 by DPS.01 Additional information added 1 Link to comment Share on other sites More sharing options...

Alchemy333 Posted March 17, 2023 Share Posted March 17, 2023 (edited) I have this issue too... obviously. Spent close to 24hrs looking for rear struts or adaptable replacements. Just rebuilt my fronts this week. Has anyone considered the idea of adding another leaf the the rear suspension to tighten it up a bit? Or would this just cause the rear end to sit higher?

Or would this just cause the rear end to sit higher?🤔 As far as I remember, there were shims available for the end of the composite leaf spring for leveling or alignment?? There have been attempts to de-arch the spring to lower the rear but I think that was done with the mounts themselves. 1 Link to comment Share on other sites More sharing options...
2seater Posted March 17, 2023 Share Posted March 17, 2023 (edited) I suspect there may be two parallel tracks for this solution. One for machining the existing strut requiring some amount of stock to get them done ahead of time or the adapter for the do it as an operation to the original or sale for the DIY. Overall it is very impressive Edited March 17, 2023 by 2seater 1 2 Link to comment Share on other sites More sharing options...

Overall very pleased with the outcome and collaboration on this project. This really looks nice. I will call the bar stock feeder shop I requested the quote from on the sleeve nut. DPS.01 did your machine shop use a tap, or did they machine the threads? (looks like machined). The reduction in overall length may be a problem as the stroke of the suspension will be 1.5" less. Simply extending the sleeve nut by 1.5" will only cause issues as the upper mount assembly will not be in compression. The insert strut has the right stroke, but the body length is shorter so the solution would be to put a 1.5" shim under the far end of the strut (in the original housing) to move the rod shoulder up by 1.5". The sleeve nut is designed to fix the 1" thread to shoulder length issue. I will try and pull together an assembly drawing later today that will show how things would work with the shim. My goal is to maintain OEM suspension geometry *if* possible. Edited March 18, 2023 by alchemist 1 Link to comment Share on other sites More sharing options...
