Service Manual Question
|
Sign In
|
|
I have a 2007 Nissan Versa, and I'm looking at the service manual. Various components have a symbol indicating "always replace this part after every disassembly." On the diagram of the front strut components the symbol appears to be referring to the two nuts that hold the strut to the steering knuckle, but it's unclear from the diagram if I should replace the bolts as well. Is there a standard practice for this?

I have never replaced those on any car. Just make sure they are good and tight when your finished.

I figured as much, as the quote I got from a repair shop didn't include the new hardware, and none of the strut replacement guides I've seen mention it. Any idea what the rationale would be to replacing those nuts?
Also, thanks for the quick reply!

They are probably self locking nuts and they are designed for one time use but if they're tight enough, there will never be a problem.

The diagram you are looking at is referring to the nut only.
I haven't done one of those yet so I'm assuming it's either an oblonged nut or a nut with nylon in the end of it. These are usually used in place of a lock washer. With all of these setups, their purpose is basically to keep the nut from backing off if it ever gets loose. Lock washers are reusable. Nylon & oblonged are suppose to be one time use just due to the locking feature.
As far as a standard....... If you want to replace them you will have to go to the dealer and their expensive. It's not a common enough practice that aftermarket part sources carry them for specific applications.

Looks like I can order them online at about $2.00 a piece. Suppose I might as well since I'm waiting on some new jack stands anyway, and if I don't I'll be irrationally worried about it. Thanks very much to both of you for the explanations, makes perfect sense now.

If I may add: When you do enough of this crap you get a feel for if self locking nuts of the sort are still self locking a second time as they just fight if tightened by hand tools. I'm not the least surprised that instructions will say to ALWAYS replace them as they can't judge what you are dealing with.
You can use threadlocker and in some places on things purposely distort a nut in a vise such that no vibrations will allow it to loosen and fall off.
If in doubt go ahead and do as suggested. I'll further suggest you get solid jack stands not the pressed metal ones with a pin and chain type. It's you life under that car forget the bargain on that! Know where to place them and of proper surface too on level area of cement. Asphalt and ground are not dependable. Double up with the wheel not holding weight (if it's off for the work but may save you in a failure,
