Default Rear Suspension Pin Removal Tricks

I am in the process of changing out my leaf spring bushings again. This is my 3rd time to replace them, but this time I can't seem to figure out how to remove the front pin, #6 in the diagram below:


Part Number 55210-01W00 for 2WD
Part Number 55210-VK800 for 4WD

I did the Passenger's Side first.
  • I used a High Lift jack on the back receiver hitch to get the rear Passenger's Side tire off of the ground (I am worried the bumper might bend)
  • I took the nuts off of the U-bolts (#7 in the diagram above) holding the axle to the leaf springs
  • I removed the rear hanger (#9 in the diagram above) so that the leaf spring was hanging free
  • I put a jack under the spring near the front and lifted it to remove the tension from the front pin, and it slid right out
  • Installed new bushings, torqued the U-bolts to 75 ft-lbs

While attempting to do this on the Driver's Side, the High Lift jack gets the Passenger's side up before the Driver's Side is off the ground, so the truck is falling off of the High Lift jack to one side.

I have the rear hanger unbolted and free, but I can't seem to get the tension off of the front of the leaf spring so that I can get the front pin out.

What are some tricks that people on here have used?

I usually place the jack just forward of the hanger and lift until I can get the jack stand under the flat part of the frame. That’s usually high enough for me, but mine isn’t a heavy duty

Do you also unbolt everything else first as I have done?

I'm not sure if I needed to loosen the U-Bolts.

you need to independently support the weight of the axle and the weight of the truck to unload the leaf spring. if you pull the u-bolts i think it will be easier to unload the pin. just remember the axle is going to want to plummet back to earth when you do that

if this isnt an option it may never come off. try putting a scissor jack under the pin with a block of wood to just take the load off slightly. you can also try putting the entire rear end on jack stands, with the stands supporting the frame and then lift the axle up until the pins unload enough. you also kinda need to account for the axle "rolling" and pinching the pin into place. basically try and unload the left and right side more or less symmetrically.

I dont know what quantity of tools you have at your disposal to make the "intricate system of jacks" but thats my suggestion

I use an A-frame and chain hoist to the hitch to lift it evenly. (My bumper is about 30" off the ground.)
High lift is too risky unless you can strap the truck to something to prevent it from moving side to side. Trees, garage, other cars...


If you have a good floor jack and stands, raise the right side and put the frame on a stand. Then, raise the left side by the frame, ahead of the front pin, until it unloads. I'm thinking that a RWD truck should raise high enough that way.
If not, support left side of the frame with a stand and move the jack to the axle. Lift the axle a bit and remove the tire to let it droop lower.

Oh I hit it like a man.

Now I'm waiting for a new one to arrive.

i think i need to do this job too. for years i thought i had a suspension clunk and that it was the axle kinda moving a little under load. that turned out to be the exhaust swinging around and whacking the trailer hitch.


are you going poly? also are you dropping the whole spring to install the new bushings or just doing it onboard?


lastly, is it just the angle or is the shank/sholder actually slightly bent?

It's a lot of labor for sure. Getting up and down, crawling under the truck for 30 seconds then crawling out for a different wrench. Dirty and all of the dirt falls on top of you when you are sweating, so you look nasty.

But, it is definitely harder to do if you haven't done this in a long time.

The first time I did it, that pin that got boogered-up above was worn in the middle like a saddle, making it very hard to remove. I took a picture of it back in 2012 that is on here somewhere:



A couple of years later, I got a new set of leaf springs and longer shackles. Since I had to take everything apart anyway, I went ahead and replaced the bushings again, this time using Energy Suspension's poly bushings.



The rear shackles were a good 2-inches longer than the stock shackles.



I am replacing with poly bushings again. They were not worn out, but they have 7 years on them. I don't want to wear a saddle in the pin again like what happened before. I don't know if the polyurethane bushings are really better than rubber, but for the price, I was able to get new bushings all around for 1/3 the price of the rubber bushings from Courtesy Nissan Parts.

Rear x2 (1 package for each side): https://www.ebay.com/itm/263825669437
Front (1 package does both sides): https://www.ebay.com/itm/263863741005

I'm not sure what made that pin so difficult to slide out.
