Front lower arm fun

I know others have had "fun" changing the arms but today was a total PITA Sad


Could NOT shift the bolt holding the rear bush … 4 foot trolley jack bar on 3 foot long 1/2" drive bar and it still wouldn't shift. Ended up taking the angle grinder to the arm itself to get enough space to get a reciprocating saw onto the bolt … ran out of blades with any teeth left about 1/2 way through so had to send the youngest off to Screwfix for some more.

Managed to snap the back end of the bolt whilst he was away then used the new blades and the angle grinder to get through the bolt at the other end. And it only took about 2 1/2 hours Big Cry

pix as promised …

So that's one side done now. Wonder how much fun we'll have tomorrow ?

I WAS booked in at the alignment place for this afternoon.

And based on the clunking, this (nearside) was the least goosed bush … but it was ridiculously soft/floppy (how DO you describe a knackered bush ? ).

Hopefully the other side won't be as bad. And if it is ? we have another 4 blades for the saw after the one in it.

At least it got me out of work on the downstairs loo project for the afternoon. Laughing

They definitely aren’t much fun if they are seized in.
I have had some joy using an air hammer to drive the bolts out.
If you can get them to move they normally come out eventually.
I always use plenty of copper grease when they go back in so at least they will come out next time.
Good luck with the other side Thumbs Up

Previous owner of mine had the bolts copper greased, it certainly made a difference when taking apart

Trust me … there is an awful lot of copper-slip on everything we replaced.

I wonder if a rotary-stop SDS drill would have the same effect as an air chisel/hammer?

Probably doing this one myself in a few weeks.

There's limited access at rear of the nearside arm due to exhaust section.

offside now done … Sooooooooooooooo much easier with decent access to nut on rear of rear bush.

Sadly, missed the slot for the 4-wheel alignment so that will have to be tomorrow now. Sad

Dont forget the front will most likely have been done at least once in the cars life, whilst the rears will only really get done once in the cars life.

Yes it does exactly that, used it on other vehicles. Depends on the space available. I have a heavy duty Makita and it packs a punch.

and the "fun" continues Sad

when adjusting camber, front offside "adjuster" didn't do any adjusting when turned. had a look and the bolt was turning but not the washer with the lugs that should keep it and bolt fixed together rotation-wise.

whipped it apart and found it had cut straight through the lugs. bolt wasn't over-tightened so this shouldn't have happened. (pic to follow - trouble uploading !!)

took car away and put the old washer on AND changed the bolt direction though the mounting bracket so it would be the welded end doing the adjustment … theory being weld was stronger than lugs.

I also did the same on the other side … just in case same issue arose.

when I looked at this washer, although it hadn't failed (hadn't been adjusted yet though ) the lugs don't appear to be the best.

Back to 4-wheel alignment garage and … whilst nearside (and both the rear ends) adjusted as expected, the offside front broke the weld Big Cry

we had to do the adjustment by jacking up the car and moving the end of the arm in the bracket with a lever. it moved easily, so i don't think it's an issue of the end of the arm sticking in the bracket. and the slide/rotate plate for the wheel moved very easily, so i don't see that was a problem either.

I now need to decide if get a replacement bolt and washer or just a beefed up washer then swap bolt direction again. I've managed to rescue the original bolt from the scrap bin too.

I could also go the route of getting a whole new bolt kit … not sure if that might be easier/quicker but if it's of same standard, will it just fail too ?

Anyone got any idea on best way to go ?
