    How do you guys torque your RTABs?

    with the suspension loaded I couldn't get my toque wrench anywhere close to that shit.

    Simulate the loading of the car sitting on the ground with a jack under the tire/hub while it is in the air.

      but with the subframe on the car or off? also I'm assuming you swap the way the nut/bolt sits? The OEM set up is to have the nut closest to the subframe bushing area

            **removed sarcastic reply**

            Installation is the reverse of removal. When installing the trailing arm mounting bolts, begin with the inner bolt. Fastener torque specifications are listed in Table m and Table o, earlier in this section. Refill and bleed the brake system as described in BRAKES.
            Sorry for being a sarcastic prick, but the only reason I resorted to posting this is precisely because the Bentley has so little information on it. Was looking for people who have experience doing this to shed light on their methods.

            Furthermore, I am aware of the importance of preloading bushings. I am simply asking how everyone here manages to do it with such limited access to the bolts.

              Prolly cause people dont bother getting a torque wrench in there.....

              What's the torque number? Get it close and she'll be right.

              Hopefully I dont attract the same childish response as you did to did to mrsleeve

                I have no problem being mature to people who are not dismissive and condescending. I appreciate you input.

                Interestingly enough, the referenced tables in the Bentley manual do not include the torque spec for the rtab. I recall it being something around 50-60ft/lbs? It's been over a year since I did this though.

                Getting is close is essentially what I did last time. Seems like that is the typical route people take on these. Thanks.

                  Sleeve was not being condescending in the slightest. Cool your jets, man.

                    You don't need to use a torque wrench. Tight is tight

                      Everyone is different of course but after a while working on cars you get a calibrated arm. Bushes you want them tight enough so the bolt doesn't come undone and loose enough so the bush isn't pinned and gets destroyed. What you end up with is a bolt that is "firm but not tight".

                        ...

                        It doesn't say shit about torquing the RTABs other than the value itself.


                        Now I am going to be condensing

                        Well thats now on you to figure out how to get access, isnt it, its been a solid decade and a couple years since I did a set. I know I managed to get a reasonable accurate torque on them when I did them with out running to the internet to figure it out....

                        IIRC the torque value specified does not require suspension loading, If it did the Bentley would specify that parameter, likewise the engineers would have allowed for the correct space/clearances or a special service tool would be "necessary" for the job ...... Theses guide books expect you to have a certain amount of common sense and general knowledge when it comes to mechanical device repair and operation. I suggest you try and use your own brain and think about your problem before you come running to the internet to spoon feed you every little step. You will end up being a far more adept and proficient mechanic and problem solver that way....

                          Apparently asking about a procedure over a year after I have completed it is "running to the internet to spoon feed me every little step" TIL.

                          I'm not asking how to finish this. I'm asking what the typical person here does in that scenario.

                          Apparently the answer is "just tighten it regardless of preload"

                          There we go.

                            there is a reason I chose the words I did. I didnt tell you to look for the torque spec I told you consult your Bentley for the correct "procedure"

                            Sorry I didnt just tell you everything.....
