  • fitting rear shocks

    I'm new to this forum and maybe the problem has already been covered , but I went to fit new rear shocks and what a nasty surprise! Top attachment is just about impossible to access. Even by removing some metal to get a swivel socket on the nut, which you can't see or feel, I gave up. Can't believe Toyota designed this.
    It seems to be impossible for DIY. Has anyone fitted rear shocks and how did you do it ? Do you need to dismantle all the carpet etc in the cargo area and drill an access hole ? Do you need a special tool to get on the nut ?

    What about using a ring spanner? I've got a 150 - you can't get to the top of the nut but there is enough space to get a spanner on it from the wheel side. A ratchet spanner makes it easier...

      Used a ratchet spanner when I replaced my shocks and springs. Harder part is doing it back up again and trying to stop the shaft from spinning.

        I've heard that on a 90, the space is very tight, needing to drill a hole from inside the cabin to get to the nut.

          Get a ring spanner to hold the nut and then wind the shock's barrel to undo it. Same for installation, might need someone to hold the spanner while you wind the shock.
          The right side isn't too difficult but the left side is no fun due to the fuel tank.
          I remove the wheel and come at it from behind and over the top of the axle to reach the shock support. An old fashioned ring spanner with a large offset is the go. You may even get a socket on it but allow some movement to get it back off.
          Check the nut size, stock will be 14mm but anything aftermarket will probably be 17mm.
          Clean all the rubbish from the mount, it's sure to be solid with stones and dirt.

            Thanks very much to peter_mcc, bassang, amps and carco for helpful advice.
            Unfortunately (?) I started with the LHS where the gap is a tiny 15mm between the chassis rail and body flange. To increase the problem, the lock nut and nut at top of the shock is then about 45mm below top edge of rail and well out of sight. Impossible to get a ring or any other spanner on the nut as it's too far down. I removed enough body flange to allow a socket with 1/2 inch drive and universal to (blindly) get on the nut but it's very insecure and I reckon if i get it off by rotating the shock, it'll be near impossible to get back on. Not sure of the size of the the nut on the Monroe shocks I'm replacing (suspect 16mm) but the replacement Commando's are 16mm Nylocs.
            I'm thinking to get access from the cargo area and make a hole which can be stopped up later. Do you know what's involved in removing the carpets and trims ? Ampts suggested this. Has anyone actually done this ? Help please.
            Cheers, Jovis

              There's no point trying to get to the nut through the wheel arch unless you have a body lift. You have to go from underneath the vehicle. You should be able to get an offset spanner on there from underneath with minimal dislocating of your wrist and elbow . Its not easy but it is possible.

                Thanks Boxy1. Have had a look at doing this, lying under with vehicle jacked up, but it's still beyond my ability without access to a hoist, so I very reluctantly admit defeat and will get my mechanic to do it.

                  Yes Boxy is right, coming at it from the outside won't work.
                  Come at it from the inside/rear. (with the wheel off)
                  A hoist doesn't help a lot, just clearly shows how impossible it is.
                  I don't like the idea of hole sawing the car either.
                  Would be different if Toyota had done it from factory and fitted with a nice grommet.

                    How about loosening the body mounts first to create the extra gap?

                      Use a deep offset ring spanner or a 3/8 drive slide t-bar with socket. fit to nut & lock against the chassis, undo shock body with large multigrips.
                      I have done this many times,
                      If the thread is rusty & you can not undo just cut through the rubber bush & shaft with 125mm cut off wheel. I have also resorted to this method on some occasions .
                      The 90 series rear shocks are a bitch.

                        Thanks folks :-)
                        I was just coming on here to ask if replacing the suspension was something doable with moderate mechanical skills.
                        After reading this thread I think I'll leave it to the pros :-)
                        Especially because I've got the extra bother of dealing with the airbags....

                          can I lower the rear of the fuel tank. Is that a possible way of getting to the top of the shock or? I had a look yesterday and wow there is now space on the passenger side but the drivers side looks easier. I wont attempt it though till I can figure out plan of attack on passenger side. Boyd
                          Any options would be greatly appreciated.

                            No worse than a 100 series. Open ender or offset ring will work. If not Sawzall/ Sabre or Recipro saw will do the job too!

                              100 series is a piece of cake compared to a 90 series. Never had to cut 100 series shocks out.
