Re: Renault Laguna 2 - Ball Joint Replacement

I'm new to Renaults so this is my first proper post

Hi folks

I wanted to add my 2p as I always seem to end up with cars that need work. Hopefully my Lag wont be one of them any time soon.

For really stuck bolts try tightening just a few degrees with a long breaker bar, then loosen.
(Righty-tighty Lefty-loosy)

But be careful - there is nothing worse than shearing off a bolt.

A nut splitter can be handy where there is space but so often its bolts that are stuck. My solution is to arc weld the top of the bolt. This puts concentrated heat directly into the offending thread.

But arc welding can be harmful to the electrics
# Disconnect the battery
# Disconnect the engine ECU
# Put the earth clamp close to the work area.

If a ball joint nut keeps spinning either split the nut or try to get some fine grinding paste into the taper and hold it together with a G clamp. The nut should then unscrew. If you go for nut splitting you have to go the whole way. The nut will compress onto the threads and be impossible to turn if you give up half done.

Re: Renault Laguna 2 - Ball Joint Replacement

A good trick to free off the nut that locks up against the track rod end is to use the 2 hammer method.....with a hammer in each hand hit the nut from both sides at the same time....give it a few good blows, now the nut should undo easily.

I've used this method quite a few times and it has always worked.
