: Removing dampers

Hi all,

Just started a major task of replacing all my dampers/springs and polly bushing everything.

Done the steering rack bushes (that was a sod) and am now at the stage of trying to remove the suspension.

The problem is - (on both sides) the top pinch bolt that holds the damper to the wheel hub will not come of.
I have undone the nut so that is flush with the end of the bolt and hit it with a hammer, but to no avail.
It just wont move at all, have tried to turn the bolt but even with a large bar it's a real struggle to get it to move a fraction.

What i find odd is that both bottom bolts just popped out with a little tap!

I have done all the usual ie jacked up the wheel hub to get less pressure on the bolt - WD40'd the bolt overnight! , prayed and lost pints of blood over it :oops: oh and sworn a bit at it !

Does ne1 know of some secret to this? BTW a larger lump hammer is arriving shortly :evil:

If anyone can shed some light on this id be eternally gratefull.

On my Aero one bolt was siezed on each side (top on one side and bottom on the other). I'd love to know how to free them. I took advantage of the fact that the Konis are an insert and cheated in a major fashion :oops:

I undid the brake caliper, bottom balljoint and driveshaft nut and took the whole hub off, since I wasn't replacing the original strut. Don't forget to use new driveshaft nuts or you'll be forever retightening them (I am, even after fitting new nuts). I did take the opportunity to fit new balljoints.

I tried heat and a big hammer and couldn't do it. My local dealer told me it would be a helluva job and that oxy-acetylene would be the only heat likely to be concentrated enough to work on such a large mass of metal as the hub. And even then, it might not work.

I intend to free them, though, since the top bearings I fitted were cheap cr4p and are rattling a lot so I need to remove the struts again and want to do it properly this time. I thought about getting new bolts (and nuts, what the heck?), then drilling along the length of the siezed bolts and passing a small hacksaw blade down the centre to cut a slot in them from the inside outwards.

Better ideas would be welcome.

Update on above problem:

Have now removed 1 of the stuck bolts.

My tip to do this :)

Basically gave it a turn with a large bar and then hit it with an even larger lump hammer, repeat untill it budges or you get p****d off with the whole idea !

What I found tho, was slightly worring : the bolt was actually bent! How on earth this could happen with 2 bolts taking the weight i don't know, but their you have it.

New bolts/nuts on order, not in till monday :cry:
So my sunday trip to see the fogees is off, damn i was looking forward to a sunday roast :cry:

Right on to the next bolt.
