wheel lugs came loose

was on the highway today and i noticed my ZJ felt kind of like it was drifting a little bit. got to my buddies house (who was following me on the highway) and i told him it felt kind of weird. he told me the left rear was shaking. so i walked over to it, grabbed the tire, and i was able to shake it back and forth. not good lol. im glad i caught it before it sheered the studs off. im just wondering what couldve caused this? the last time i had the wheel off, i did put some antiseize on the studs, but that shouldnt cause them to loosen. i always tighten them in a cross pattern, so i know the wheel was evenly tightened as well. any ideas?

Dont put the full weight of the vehicle down when tightening lugs, as it can bind the wheel. Proper torque according to the chart at work is about 115 pounds.

Don't know how far you drove or how severe the shaking, but the studs may have already been stressed. Who knows, a few more miles and the studs may have snapped. Might be worth replacing the studs. my .02.

If you put anti-seize on and then torqued to spec, you over-tensioned a lot. The torque specs in the manual are dry torque.

Doing final torque with the vehicle on the ground is fine.

i didnt torque them to spec, just tightened with an x bar tire iron. always done it that way and NEVER had a problem before.

im not sure how long they were loose for, and i couldnt feel it shaking, just felt like it was drifting a little. that mightve even been because there was a heavy cross wind on the freeway.

How do you tighten the lugs with the wheel in the air and keep it from spinning if you dont have an impact gun??

I know what you are saying but the point is valid, and definitely possible. At least get all lug nuts tight as possible.

Also if it was in a 4x4 mode (part time) the rear parking brake will lock the front too

Just snug up the lug nuts and then let down the jack a little until the tire is lightly resting on the ground then tighten them up.

Jam a brick or rock or something under the tire to make it not spin.... Also make sure the wheel is flush on the axle before you tighten them. If the wheel's not sitting properly when tightened it will come loose.

Wheel studs are one of those little routine inspections you should do fairly frequently....Like checking the oil.
