How do I know I have a bad shock?

My rear passenger side sets lower than my driver side back. It’s about 1.5 inch different. I have 6 in RC with RC shocks. Any help please!! Thanks in advance

 

What i would do,

Make sure both front tires are same psi. Do the same in the rear.

Then measure all 4 fender heights. Maybe the driver front is too high? Get all your measurements then you’ll be able to trace the issue. How is the rear lifted? The shock is not the issue

 

Shocks won’t affect the ride height when they go bad.If they do it would be minimal. An inch and a half difference is huge. How long has it been doing it? Did you just recently have the lift installed

 

Psi is same in all 4 tires. I use blocks for the rear lift

 

Just noticed it as I was washing my truck. I have about 6000 miles on the lift.

 

I have RE checked all bolts on the rear. Everything is tight

 

Standby

 

Passenger side

 

Do you have lifted shackles in the back?

 

Driver side

 

No sir just blocks.

 

I had the same thing on the passenger side because of my leaf springs. I put a shim on top of the driver coilover and it balanced everything out.

 

Yes stock

 

So it’s not a shock issues more like a spring?

 

He’s having the opposite. His passenger side is an inch and a half low in the back. Putting a shim on the drivers front would make that worse. It’s possible he could need a shim on the passenger side.

Op. Make sure you checking all these measurements on level ground. Try moving your truck and see if the measurement changes. Definitely check for discrepancies in the front because that can affect the way the rear height sits.

 

I will double check right now and send the measurements

 

29.5 on both fronts.
30.75 on driver side rear
28.5 on passenger side rear

 

This is my 1st Tundra also. I understand the driver side due the 38 gas tank. I am lost.

 

I replaced my rear shackles with some coachbuilders and some polyurethane bushings. After inspecting the old shackles and bushing set up, there are serrations on the bushing that bind with the rear shackle. Like little teeth on both that make the shackle not articulate. It wouldn’t be impossible for those to be bound in a lower position. Very shitty design Imo.

 

But I have only 8000 miles on my truck. They should not have worn out. Is it safe to drive??

 

This is really bizarre. Is it possible that the shackle is dramatically tighter on the driver side and thus doesnt flex back the same?

Can you jack up the rear by the hitch and see if it settles down the same way?

 

Not worn out but maybe they were tightened down while the truck wasn’t level. Just throwing it out there man. Your scenario sounds pretty odd and I’m just trying to brainstorm here LOL

 

Yes I can jack it up. But I have a very dumb question!!! They did aliment on my truck when they rotated my tires. Could the aliment done something???

 

Thanks for the help. Just pissy me off. My and are going out town tomorrow and we was driving the tundra

 

Here’s my old shackles. See the little teeth?

 

As long as everything is tight you should be safe to drive it. An alignment won’t cause something as dramatic as this. And like you said the front is measuring out perfectly.

 

Thanks. Iam jacking up the rear now
