any advise is welcome

 

Not to be rude as I do not know your skill level and what tools you haver but if you have to ask how you may want to consider a shop.

It may prove to be cheaper and safer in the long run. I am sure it would not be too expensive as it does not take that long.

 

i know how to do it i didnt know if there were any special torque specs or to just make sure the bolts are on good and tight
