Was thinking today... could it be bad shocks? Or shocks starting to go bad?

The answer to that question is a possibly yes

As I advised previously........Any component that is linked to the road wheels is a suspect until they can be ruled out.

It is so annoying when you have to spend money to change parts on a hunch........only to discover that the problem persists.............als o the

parts you take off might still have some mechanical life still in them.  I would also advise you to chat with a few mechanics to see if they have

encountered  similar problems or know of a fix.

You will not be obligated to have them fix it....but some are a fountain of knowledge from years in the trade.

I am sorry I cannot think of a possible solution.........but I am sure someone in the garage community could have the answer.

I wish you well.......and you will get there at some point sooner or later

Good luck.

Cheers, appreciate that!!
Alright I will plan to get another opinion on this before changing anything else.

Hi wim,

Sorry to read of your issues  :(

I suggest you have your hubs checked for wear and out of round by a specialist.

Good luck

Got some progress finally... I think.

Loosened the ARB bushings quite a bit and this improved already. Still not fully solved but definitely more bearable.

My feeling now is that although there's no play or worn parts, suspension might simply be too stiff... going to check coils and shocks next.

OK so I do not find anything else. If any, the shudder happens when going over uneven roads - on flat roads nothing happens on the steering wheel. When the wheel hits a bump, it jerks the steering wheel.

On top of  that, the strut has been overhauled completely on both sides (new shocks, new coils, new bearings, new top mounts...)
Had another re-alignment check, but to no avail.

I'm really puzzled...

Quick question though: should there be any play in the top mount when the car is lifted from the ground?
I can feel this on both sides - its not there with my other Calibra (didn't check this one on the road yet).

Hi

The last part of your question reminded me of when I took my Cali for MOT..........The tester passed her but queried looseness as you described when the strut was lifted.  ::)

I then remembered that prior to the MOT.......I had turned the top mount that rests on the suspension turret upside down because they looked neater.Lol

When I asked the tester if this would mak a difference he said possibly.......so we fitted them the original way and he tested and said it was fixed.

I don't know if this has anything to do with your problem.......but goes to show how correct assembly is important.

Thanks for the reply. Indeed there was a larger than usual gap between the top 'washer' and the car body. This was because of the new nut supplied with the shocks having a higher head. I refitted the old nuts and now that problem is solved!

Still having a steering wheel shimmy... :-(

"When the wheel hits a bump, it jerks the steering wheel." That is bump steer by any name you can put it. Something wrong with your geometry of your suspension either you have the wrong arms fitted or bent or your chassis has been hit (which I posted before about hitting traffic islands). You need to get the tape measure out and find a level place and then measure from the centerline to all points of your suspension and to the ground each side should be identical in height and length (fore and aft position of the wheels). Calibra front subframes do shear the mounting welded nut under the drivers foot well - check if you can move the front subframe around. The attachment points of the steering rack also crack and split causing movement and lastly the drivers foot well bulkhead metalwork also splits (at the brake pedal mounting I think) - carpet out job I think but ask first someone who has had these problems.

ET49 is the fitment for Calibras the ET44 may be OK but accentuating the problem. The videos of your tyres show a 5mm buckling, you are never going to get good handling with those wheels. Wheel alignment doesn't check if your chassis is twisted or your wheels are buckled.

Hi

Electric geen has made a good point regarding the geometry...i.e. Bent chassis .if this turns out to be the case .....this will cause big problems

to the correct running and can cause all sorts of Vibration....squeaks.... and strange noises so it is very important to rule this out.

We are all on a roller coaster ride with you........there can't be many more possibilities left  ::)

When we as owners modifie our cars we change peramertures that designe engineers have carefully inserted into the car to get the best and safest option available.

If done correctly...modifying .has it's benefits.......however done wrongly....i.e.....Lower ed susspention......differe nt wheel sizes and offsets etc can introduce negative results which change how our cars behave on the road.

A friend helped me do my first Clutch change with engine out.  On reassembly he used a large breaker bar to tighten the Subframe bolts and by overtightening he broke the welded captive subframe bolt which caused an agrivating rattle. ::)

I had to cut a hole in the near side footwell to get access  >:(..........the nut was re welded...and the fooking cut floor panel.  >:(

Sorry to digress...but just to show that small mistakes can have a big impact.

Fineally have you changed the Constant Velocity joints......some times a physical inspection does'nt identifi internal problems.  This happened to me when I removed the CV joint the center ball bearings etc made a dive for the concrete......So when I inspected the internal spiral ball bearing channels I could see gouged out grooves which were hampering the smooth travel of the ball bearings.

After re-mewing the CV joint complete.......result 8) no more noise.

Hope we sort your problem out soon m8 .......been having bad car dreams Lol.....the other night my cars complete suspension.......wheels. ..hubs

etc parted company........I hope it remains a dream Lol........Don't have nightmares  ::)

Yeah no worries there, I appreciate all the help I can get to try and solve this!

I do not hear any strange noises or rattling... everything at least seems tight. I will do a more thorough inspection of the subframe and steering gear mounts and report back.

The issues I have date back from say a year or so, but I cannot pinpoint it to a serious hit or particular part replacement (lower arms, tie rods & ends, etc)... seems something that grew over time.
The strange thing is that some days it does better than others.

EDIT: what do you all think about this though?

Just seen the video :o Very scary, that is the steering rack that should be bolted tight to the bulkhead with two clamps. If the clamps are tight then the steering rack clamps have come away from the bulkhead. That steering rack must be fixed and immovable otherwise the left wheel (for example) hits a pothole and transmits it through the loose steering rack to the right and jerks your steering wheel too. You may have found your problem there. (There are aftermarket kits that brace the steering rack because of the flimsy metal it's bolted too. Saabs are really prone to it and they share the same underpinnings as the calibra)

Thanks for the comment, I hope this is it! I have a spare (2nd hand) rack that does not show this play... a job for the weekend :)

The rack fixation points themselves are OK and tight. It looks like play within the rack itself.

Hi I got fingers and toes crossed ;D

As electric green said.....you may have found the culprit......that naughty little Gremlin had to be hiding somewhere Lol

Electric green ......" You're the Man"  you are very knowledgeable.......and that makes you............My Best Friend 8).....well done.

If you are not a professional mechanic......then you should be.  Can't wait for you to get back to us wim.....hope this loose steering rack sorts it.

Not a mechanic, just an contract engineer having worked for 30+ companies.  wim_vg has a complete nightmare on his hands and it's easy to throw in the towel and move away from Calibra's - and I don't want that to happen, nobody here does, so we all try to help with the little bits of info that aren't always in the manuals or hidden away online. Sometimes being so close to the problem makes you blind to the solution and a problem shared is a problem halved.

After writing this I am going to take my Calibra out for a run with her indoors (who likes the Calibra more than me (it's a women thing, they just love Calibra's)). I have a company car provided  by my employer after they saw me driving to work every day in the Calibra and thought it would fall apart at any moment it was that old - it never did - but I appreciate the freebie vehicle, but then you get in the Calibra and think today's cars are not that nice to drive with their diesel turbo lag or comfortable either, far to high and certainly not very attractive.
