If the nuts on top of the struts are tightened with an impact gun. Will this cause strut mounts to break pretty easy?

 

Why don't you just use a torque wrench? If you over tighten the nuts then you have a chance of stripping the bolts which could pose a problem.

 

The dealership swapped the strut out and must have used a impact gun to put them back on. When I went home to put my strut bar back on, the freakin' nuts were so tight that they started stripping and I stopped until I could maybe try a different socket or wrench it was the correct size. I want to know that if by them tightening the nuts so tight does it make the strut mount break easier? I am now hearing the same sound as I heard before I brought it to them. Remember I'm in New Orleans and we have speed bumps on our Interstates.

 

Still have that strut nut problem?

 

The dealer uses torque sockets.
They seem to know how to tighten it.
My friend was tightening his strut bar on he '95 240SX SE and we told him it was 80 Foot LBS. He thought we were serious and he ripped off the nut with the torque wrench.

 

That's mean, yet at the same time, incredibly funny.

 

Never trust an impact gun for things that need a more acurate torque setting such as your strut towers or wheel lug nuts.

Nissan specs are...

Front Strut Tower:
32 ft. lbs - 38 ft. lbs

Rear Strut Tower:
18 ft. lbs - 25 ft. lbs

Wheel Lug Nuts:
72 ft. lbs - 87 ft. lbs

Damages can happen if the nuts are tightened too much.

Peace.

 

Well I finally got the nuts off. I had to hammer a socket on the somewhat stripped nut. I also used a breaker bar to break the nuts. I do still however hear a rattling sound coming from the struts. I'm still wondering if overtightening will cause the strut mounts to break prematurely anyone know?

 

The bolts will snap if they are overtightened. One member used 85 ft lbs and snapped almost all of them. Yes, the strut mounts will break if they are overtightened.

 

That member was me..using bad info that I got..35 ft lbs..not 80..I snapped 5 of the six off (they didn't snap off right away..after one did, then i checked the rest and they broke off in my hand)
