    Hey guys been doing research trying to figure this out why I am getting a popping sound that i can feel , it sounds like it came from my left and right side different times when turning into my driveway and when I turned around.

    I am wondering if my main shock bolt on the top hat is not tightened all the way as I had a local shop assemble them for me.

    Can you look at this photo, Is there suppose to be threads showing on the center bolt?

    Yes, mine has over 3/4" of threads above the nut; however, your nut and shaft thread size do not look like my 5100 at all, maybe its just the picture angle, but your nut looks huge and shaft looks smaller than mine.

    So are these the Dobinson 2" or 3" lift coils? Are you using the 0" bottom perch setting?

    The 2" Dobinsons on the bottom perch.

    Yes stock lift other than the 2" gain from the dobinson coils. Stock skid plate.

    The part sticking up past the nut in the photo is the part you hold onto to stop the shaft from turning, No threads from the bolt are visible.

    Sounds like this may be my problem? how far should I snug the bolt down till it stops?

    Thanks guys

    As I recall, you tighten it until the rubber bushing begins to bulge.

    Regardless of springs you should see about this much thread count from your shock shaft. This is 5100 on the middle setting

    I think the issue is you have a 2000 model 5100 - they must make the shaft completely different; mine looks like what bravohook posted where its threads all the way to the top and a smaller nut; the 5100's for 1st gen's must just be a lot different.

    If you are good at gauging torque by hand then maybe just turn the nut with a crescent wrench and see if it feels close to the torque spec.

    This is how mine looks too; I think the issue is that he has a 1st gen Tundra and the 5100 model for 1st gen's is much different apparently.

    Hey guys, So i tightened the top nut to torque spec, it was not even snug at all, I'm thankful it didn't come apart while I was putting them in, I will be leaving 1 star for that shop for sure now, thought they were good but clearly not.

    I also snugged down the sway bar end links, gonna go test it out now.

    Yes a non-torqued top nut which leaves too much of the shaft length for play is a known cause of a "popping" noise, so that was likely your issue.

    The torque on the 07+ 5100's is only 34-Ft-Lbs though - so just make sure you haven't over-torque'd it.

    heard a few pops but not as hard as before.
    I did circles in the gravel both ways, made no noise,
    Going up a hill and turned at the top I heard a little pop,

    is it normal to have some little pops? and pings? from longer than stock coils.
    I have not done aliment yet , waiting for new tie rods and end links I ordered to put on before i get one done as it cost 100$ for alignment

    Turtle, are the nuts tight on the ball joints that connect your upper and lower control arms to the spindle? Have either of the perch rings on the 5100's failed? If you jack the front end off the ground are the coil's tight and held in place if you try to pull them hard by hand? I would just inspect the obvious.

    I’ve not tried the Dobinsons, but I’ve had quite a few different Bilsteins and springs and never any popping noises. Double check the torque on any bolts that were removed.

    I did replace the lower ball joint with a oem, I torqued the castle nut while the car was lifted. Should I have torqued the LBJ castle nut when the truck was on the ground with the weight? or would this not matter?
