Hi , reading through many threads this seems a common problem but know one has an answer. Is it the trailing arm bushes worn or the large bush that connects sub frame brace to the sub frame. The car has not been lowered so the camber/toe in are factory. Interested in your comments.
 Many thanks

Hi, still waiting for the rear bushes, 176 views and no comment ?

Hi Andrew, many thanks for the reply, I was beginning to think I was the only person on this planet. Using a spirit level ( I know its not accurate ) I found the top of the tyre leaning in by 5mm so as you say a camber issue. I have seen the adjustable bushes you mention but as my car is not lowered I hoping the new bushes will restore factory settings. I am still waiting for the new bushes to arrive via e-bay. These I think are getting a bit scarce as I tried 3 times from different suppliers to get mine. When I change them I will update you on there condition to see if that was the problem.
Many thanks again. 

Hi,
 Thanks for the reply, I do agree with your assessment about changing all bushes, however as the o/s rear tyre is not showing any wear I am using this as a bench mark and not mudding the waters by changing all bushes. As an aside, last year I changed the large sub frame bushes from Vauxhall ( cost arm and leg ) When done I will take it to have it laser tracked if OK I will do the o/s bushes. As for the sub frame the car has been garaged for most of its life ( I have owned it for 20 years) is in good condition, but will paint the trailing arm when removed.

Hi, Electric green.
 Many thanks for the info on poly bushes but I decided to use standard bushes , a however I did consider using them as they seem easier to fit than the standard bush which at the moment there seems no tool around to remove or fit. There is a tool for Vectra's rear 45mm 'rose' bush, same size as the Calibra's trailing arm bush but as there not a lot of 'meat' around the bush housing the tool has to be a dead fit.
 Many thanks

Hi all,
The sorry tale continues. I unable to source anywhere the correct Vauxhall bushes part number 90223456. The after market parts that I bought are made by Moog but have the wrong dimensions, to small, all other makes, Febi,Firstline,Delphi and many others all give the same size and look the same and state they are a replacement 90223456 ? I know I can go down the Poly bush route but I want to keep the car original. Has anybody fitted after market bushes to their trailing arms, if so what make did you use or maybe have unused original bushes sitting around.
Many thanks

Sorry I can’t help as such. You could try to contact Autovaux - they’re usually very good on parts.

Hi, just thought I would give an update tyre wear and rear trailing arm bushes. Managed to obtain 2 original bushes just before Xmas. To my surprise  there was not much difference between original and pattern parts. I noticed a slight noise from the rear bearing so I will change the bearing and check the brake back plate to see I its rusty where the brake shoes retaining pins go. Coming back to the rear bearing I understand it is a pig to remove. I have searched this site and Calibra Net for any pointers. Unfortunately there isn't any just that its a nightmare to do. I have checked YouTube there's nothing on Calibra bearings but if you put in Omega B, which shares the same bearing set up, there's about 4 how to do's video's. I am not going to use hammers but invest in a press and do it as per manual. Keeping my head down while this Covid storm is blowing and do the job when things settle down and its warmer.
Cheers

Hi, Part 2 I forgot to mention that after I removed the hub I took off the hand brake shoes and removed the back plate. I have read somewhere that the 10mm Torx bolts are made of cheese and they are. I managed to undo them just before the splined tool began to strip the heads. I checked over the back plate and checked the shoe retaining pin holes, all ok. With the back plate out the way it gave me great access to set up the bearing puller. After I fitted the new bearing I removed the trailing arm. This still involved undoing the sub frame bolts and jack up the body so I could remove the bolt nearest the sill ( the bolt head hits the body work) With the arm out it was just a case pulling the old bushes out after cutting the lips off the old bushes. The tool I used was the old Cortina void bush tool , remember them ! worked a treat. With the bushes in I used plan A to fit the hub back in. The plan was to support the back of the bearing with a piece of tube, rest the lot on a steel plate and tap the hub back in. I found it impossible to hold the arm and try and tap the hub back in straight and not damage the bearing. Time for plan B. I found if I lightly tapped the hub in just a couple of mm there just a couple threads showing so I could screw the nut back on. I was worried that I might strip the threads but it was enough to start and wind the hub in. I used different pieces of spacer until the hub was back in. This just left ABS flange to fit. It was easier to hold the arm and rest the hub on the steel plate and tap the flange back on and refit the nut. There's know doubt that if you had a press fitting the hub would be a piece of cake. I would not rely on just using the nut I was lucky that the nut did not strip so I would not recommend it.  Just a note on the nut locking ring. I found it a pain to fit , the idea of the lock ring is cup shaped and when you tap it home the outside edges bite against the flange. If you don't tap it in square the edges bend and it falls out, great. After bending the edges back I found 40mm piece of tube and tapped in square so it locked in place. I will fit it all back tomorrow and see how it goes.
