Thats preety much it.You really should consider getting a gregorys workshop manual for doing jobs like this.These manuals have all the various nut and bolt tensions listed, and gives the removal and fitting instructions in detailed step by step form,you cant go wrong,and you know the job is all done correctly. Well worth the $50.Try not to get the haynes or max ellery manuals,the gregorys is much better,or even better again,a genuine factory manual,but they cost heaps more.Hope this helps.Cheers.
