TF lift install and drivers side 1/2 inch higher than passenger side

Hi - need some help here please. I just installed the TF 2.5 Coil Lift with shock adapters on my 2014 JKURX and appeared to have no issues. However, a week later I noticed that the driver side of the jeep is about half an inch higher versus the passenger side. It appears to be a full half inch higher on drivers side as measured from the level floor to bottom of fender on the rear. I also did check the from measurements and the drivers side on front is about 1/3 inch higher (measuring both sides of the front floor to fender). I also did install 315/70r17 but all four tires measure same from floor to hub center and floor to tire top. I then went and measured both the rear shocks and measured from bottom bracket (below the bolt) to the lip of black plastic upper shock cover (on both rear shocks) and the passenger shock to plastic cover measured about 1/2 inch less than the drivers side. I shock the vehicle and stood on both sides and then moved it and repeated the same measurements. Could it be the shock or the lift? All four springs appear seated correctly with factory rubber pieces on top of each coil. Any advice on what to do to validate the issue and correct would be appreciated.

I could be wrong, but I believe it's to compensate for the weight of the driver. Try sitting in it and have someone measure the same spots.

No.

Teraflex front coils are rated the same for both sides. The rears are rated the same as each other there too. Your jeep is lower probably because you have a full or nearly full gas tank. Gas weight in the tank commonly weighs a jeep down and causes the lean.

Remember, you have longer coils in there than the shorter more compact stock ones. They are going to give (compress) when weight is introduced. Different amounts will net different results.

Thanks for the replies. I actually only have 1/4 tank of gas in it when i measured but I also noticed it when I had full tank (but was out and did not measure at the time). I read some older posts saying some jeeps lean and some don't. I am pretty sure mine did not lean prior to the lift as I measured it (and my OCD eyes would have noticed it). I emailed TF but probly won't hear til later this week. Is it worth considering swapping rear spring to opposite side?

Did you keep the factory isolators atop the new coils?

Did you get the bottom of the front spring in the little grove on the spring perch on both sides?

Great questions -and yes, i just checked and both front springs are in the little grove (as i noticed that when taking out the OE springs) and the isolators appear seated equally atop all 4. The rears appear seated well top and bottom too. Just confused because I dont think I had this before. Before I decide to switch the rear spring, I guess I can wait to hear back this week from TF unless you have other things I can check in the meantime. Not feeling like swapping the springs just yet. Again, thank you.

Tweak - Thanks, I will try and do that this week and reply back. What do I do if it does lean to right as you think it will? Any easy way to correct?

Just looked at my TF 2.5 coil lift measurements. I was a quarter inch higher on the driver's side prior to lift, front and back. With the lift, driver and passenger side are the same height rounded to the nearest quarter inch. I have 2014 Rubi with a hard top. Gas tank is usually between 3/4 and 1/4 full (I live in the sticks and usually get gas in town. I burn some on the way home and need some left to get to town).

Hi Tweak,

We're not talking about modifying a jeep to induce a lean here. Out of four jeeps that I've owned only one leaned and it was dependent upon the amount of gas in the tank. 3 did not lean at all.

Not all lean.

OP, did you retain the isolators when installing your new coils?

Esp - yes, I re-used the factory isolators on top of the new coils. Looked tonight and they all 4 seem to be correctly in position. What baffles me is I did not notice this lean right away after the lift install so could it have occurred in the last week since the lift? I just did drive it to the beach and back and had a family and a bunch if gear in it. I'm thinking I may have had heavier stuff on passenger side on way back (plus in the car the night before we left). Drove great but I really noticed it on way back whole looking at the jeep before we left and then again at gas station, then measured when I got home after unloading. I will re measure tomorrow after it sits all night un loaded.

How about some pics of the lean and the suspension components too. Seeing how things were installed would make it easier to accurately diagnosis.

Macaw1us - was/is yours shorter on driver side pre lift or post lift? if so, what kind of lift?

I just installed the same lift Saturday but I opted for the TF 2.5" with new shocks and I'm just shy of 1/2" higher on the driver side as well. We rechecked and everything looked to be fine. Have driven it on local streets and at highway speeds and it is smooth as can be. I was under the assumption that there would be some sort of settling process involved. Ill have to keep tabs and see what you find out.

My OME springs were of different lengths. The front left is a bit taller to account for the driver's weight. (there will always be a driver, perhaps no passengers) and the right rear is taller, to account for the torque when hitting the gas. I don't know anything about your lift, but perhaps they are the same and springs got put into the wrong spot? Just offering ideas, not accusing. :-)

Mine is a 2014 JKUR. From the dealer mine leaned passenger about 1/2 inch. I have installed OME 2" heavy coils and still have the 1/2 inch lean or so. I almost never go less than 1/2 tank of gas and have always assumed it was the weight of the gas causing the lean.
Doesn't effect it's drivability so I have learned to let it go.

Measure the coils, not flares/body which is not accurate.

Front (pic)

Rear .. Measure from bumpstop base on axle to metal cup (the lip) = 5" stock.

I just double checked mine. I'm at 12 inches on the passenger front spring and 12 1/8th on the drivers. Shock measurement is also showing just slightly higher on the driver's side. But an 1/8th is essentially level. I've been driving mine for about 6 weeks so it's probably settled. If mine is any indication, a half inch is not normal.

Now go measure ground to flare like the OP. See what you get for comparison.

38 1/4 passenger, 38 3/8 drivers. OP is running 315/70/17 but I'm on stock Rubi tires. He should be about 1.1 or 1.2 inches taller. He's 1 1/4 inches taller on the passenger side (looks about right) but 1 3/4-ish on the drivers (too much?).

You subtract those to determine lift height?....I need to do that.

Hi all - thanks for telling me where to measure. I just measured as described here ( bump stop base to cup lip) and got 7" on rear driver side, 6.5" on rear passenger side. Front from spring ledge to back of spring tower was 12" on driver side and 11.75" on passenger side. I guess this means the spring in rear passenger side is a bit softer??

Also, teraflex emailed me back today and said " Its the gas tank on the pass side. Its common on all JKs, theres a thread in the JK forums called Jeep lean. Its more pronounced with a full gas tank. A spring spacer placed in the right rear will generally level the Jeep." I then replied and they said "You can try swapping the springs. If the jeep leans to the driver side at that point I would say one or both of the springs have an issue. We would cover that and send you new springs. We have found adding just the rear spacer does the trick, and doesnt cause any issues. Send me your address and Ill send you a spacer."

Any advice on What I should do?? Take the spacer, swap the rear shock?

That's up to you. I would take them up in it.
Remember .. With the driver the jeep prob levels out.

I didn't measure my rear. I can do that in the morning but I've only got a quarter tank. Take the free spacer and while you wait, swap the rear springs. See if it make a difference. Or get someone to measure with you in the drivers seat.
