Default How much to tighten? help

i'm a noob.
so i'm going to be changing my stock springs to H&R sport springs, and i just have a question about tightening my bolts (abs, brake, and strut bolts)
is there a limit to how much i'm supposed to tighten them? or do i just tighten them fully as much as i can? thanks. will be using a socket ratchet to tighten.

All these bolts have specific torque specifications.
A proper torque wrench is what should be used.

If asking these levels of questions, you really shouldn't be doing this kind of work without a knowledgeable helping hand with you.

Only as much as needed to turn the top hat nut several threads so when you release the compressors the spring does not go flying.

It sounds like this is your first time doing this. Do you have someone who has done it before for help? Perhaps go to your local chapter forum and offer someone pizza to help you out.

I'd suggest looking up how to videos, read write ups and read some more.

Overall it's not that hard to do, but it can be screwed up.

Oh and you will need an alignment when you are done.

That would be very bad. The three studs at the top of the strut will shear off easily - they only take 15 lb/ft of torque. The ABS and brake line bolts are a bit stronger but will still get damaged if you go crazy. At the other extreme, the big bolts holding the strut to hub require a lot of force, and "as much as you can" might not be enough unless you have a long ratchet (or are very strong).

You don't need to invest huge amounts in a top quality torque wrench, many people use cheap ones from car stores. I use the Sears ones, when I can get them on sale. You will need one that goes to 150 lb/ft for struts - I'd recommend a 1/2" drive.

Compress them until it fits on, but I don't think it matters if you go too far. I run my spring compressors all the way down until they won't go any further and I've never damaged a spring. I use this type:



There are some very good posts with lots of detailed instructions and pictures. Find one and follow it carefully. Struts were about the first thing I did and it took me ages because a) I struggled to get the rear struts undone, b) I worked very slowly and carefully.

I hope you have a secondary hand to help and watch over you, because I see an improper install/problematic future for your little project.

There is a lot of reading to do in the DIY's that are already created. Please look them up and read through them several times over. Make sure you have the proper tools. Also make sure to mark your camber bolts with a paint pen or similar before you unbolt everything. Make sure to get an alignment asap after.

If you would wait a week, I could help you next week. But as it is, don't hurt yourself.

Nice offer, and yes, but really, the torque spec for those bolts you listed doesn't matter. Just snug them up and done. Not too loose, not gorilla bashed. Easy.

Brake and strut bolts don't matter?
Strut to knuckle just snug?

I don't think you read the original post correctly.

The torque numbers are good to have, but you can survive without them

ABS and brake lines should just be snug- there's no real force on these, use a little blue Locktite if you're worried.

Strut to knuckle should be firm to hard- they're hardened bolts, you won't over-torque them with a normal wrench, but consider how you'd deal with them if you had to take it apart again tomorrow.

The strut top hats should just be firm- they're softer metal, you don't want to strip them

A torque-wrench is nice (and I use one) but a good sense of touch with consideration to the metal you're working with will get you there too.

Good advice for an experienced person, terrible advice for everyone else.

Exactly what I was thinking!!!

Man, just read the original post and its pretty apparent the OP is very green. You can't assume even a moderate experience level.
