I am installing King front and rear shocks tomorrow and when reading thru the instructions provided from King it reads to tighten upper and lower bolts and torque to factory specs. I cannot find anywhere that tells the factory torque specs for front and rear shocks, can anyone help me with this?
 
I had looked in this file and did not see anything for shocks, I appreciate the response just don’t believe they are listed here
I have a suspicion they are in points 1 to 5, which were not posted. Sorry that is all remember seeing.
 
M14 x 1.5 10.9 Plated bolts have a torque listed 158Nm? ( not from Ineos) this is what I did. Going by how tight they were to remove I would say this is still under original install spec.
Only did mine last week and rechecked today after 126 miles all good.

Hey Scott,

I just called my local Ineos Dealer and they looked it up in their Ineos portal and informed me that the torque spec for all 4 shocks (upper and lower bolt) was 275NM, which equates to about 202 ft lbs. Seems really high to me but I guess these rigs are designed to be hammered offroad 🤷🏼‍♂️ Hopefully this is helpful to everyone!

202 ft lbs is insanely high.
 
It is so high as to strain credulity. There is no engineering reason for a shock mount torque spec of 275NM on the Grenadier, it is not an earth mover. It also exceeds the standard maximum torque rating of ~217NM (per Fastenal, but varies by source) for a M14x1.5 10.9 bolt with dry assembly.

Which is why I snugged them up the same as every other vehicle I own. I can tell you for certain mine were not torqued like that from the factory. I broke mine with a standard 1/2" ratchet by hand.
 
The wheel nut torque for the same 10.9 bolt is 160Nm.
275 is not far off "righty tighty - oh fck" 😉
 
I suspect the actual torque spec is 175NM or 130 ft lb. If 275NM is the specified torque per the dealer documentation then it is an error that needs to be corrected. If that much torque is actually used it will likely cause permanent deformation of the bolt and result in premature failure.

I hope you are right as i’m not sure I can apply 200 ft-lbs torque, especially not while laying on my back under the car 😂
 
I took delivery of a set of King shocks. I watched the videos of a couple of installs. The instructions looked easy peasy. I'll start with the rear shocks because that seems the easiest. Off I go to the parking garage with the shocks and my Halfords socket/wrench set. Removing the wheel, easy. Removing the plastic shroud - bl00dy hell, fiddly as anything. Pulling on the plastic around the wheel arch to remove it feels uncomfortable up to the point where it just comes loose. Getting that lower shock bolt loose wasn't happening. I had to go back upstairs and get the Milwaukee ugga dugga. Wouldn't you know it the only size I needed wasn't included in the impact socket set I had. The Halfords 24mm socket did the job but it paid a heavy price. I got the old shock out and was feeling quite pleased with myself. Commence assembly! Erm, yea. This is when I realised I didn't have all the right tools. The bottle jack that comes with the Grenadier does a decent job of lifting the axle. Jack stands under the axle for safety but the little bottle jack wouldn't reach anything higher. The King shocks are pressurised and took my full body weight to barely start compressing it. There was no way my scrawny ass was going to be able to compress the shock to get it to fit in the shock mounting brackets gap. I didn't have a way to adjust the distance between the shock mounts. I ended up using ratchet strap to compress the shock. It worked but it was really fiddly. Not recommended.

I've got a digital torque wrench range 17NM to 200NM. I looked up the torque specs for the 16mm bolt. There is a 10 stamped on one of the nuts so I'm assuming that means grade 10. The chart said 302NM so the 275NM figure from the Ineos specs seems about right. I set the torque wrench to 200NM and I spent 20 minutes trying to get the lights to go green. I wasn't successful. I ended up with the jack handle on the Halfords socket wrench with as much effort as I could muster and I think I might have reached 200NM but no way was it anywhere near the expected 275NM.

I never give up so I finished installing the rear shock on the right side. I'm a believer in loc tight so I'm sure nothing will work loose. I'm off to Totaltools tomorrow to get the tools I need before doing the other three.

I enjoy working on the Grenadier. Every panel I take off or bolt I remove makes me feel like I know it a little better. It feels like it's going to be a long relationship. :-)

When I fitted mine (rear) didn't remove the inner plastic wheel arch, it is doable, and for the fronts used an oscillating saw to do the cut out in the inner arches, keeps it neat.
 
I got a quote to do the other three shock absorbers. I was quoted 2 hours each @$155 an hour. No qualms about the $155 an hour but 2 hours to replace a shock absorber? If I buy a floor jack and throw it away it will still be cheaper if I do it myself. I know, any excuse to buy more tools!
Thanks for the tips about the plastic wheel arch. I think I can get away with not removing it from the rear and I've got a saw that I can use to cut the front. I can't wait to get my hands dirty this weekend.
