[Healeys] Top Trunnion Bearings

[Dave Schweninger]

Hi Gary.
I assembled my front end during a total restoration. All the parts  
were clean and Dry.
I think that replacing the thrust bearing could be done fairly  
easily. I would jack the car up with the jack under the spring plate  
so the cars weight is on the the cars spring. Remove the backing  
plate. Crack the swivel pin nut loose (after removing the cotter  
pin). Remove the bolt that goes through the shock "A" arms and the  
upper trunnion. With a little persuasion you should be able to pull  
the trunnion out pivoting at the lower trunnion, Remove the big  
swivel pin nut and the spindle will slide right off.
Clean everything up. Really clean and dry. Now is the time to check  
everything out for wear, slop and all that good stuff.
The new bearing slips on the trunnion after the spindle and the upper  
trunnion goes on top of that.
Healey Spares undoubtedly give instructions on how to sort out the  
shims. I use a feeler gauge between the trunnion and the spindle to  
measure the clearance.
I'd replace the upper trunnion bushings and the Cork seal on the  
covers on general principals. You may have to loosen the clamp bolts  
on the shock "A" arm to get the new rubber trunnion bushings in. the  
clamp bolt on the shock shaft acts as a key and should removed to  
allow the arm to slide out a bit.
I just discovered you have a BJ8. Removing the disc brake is a little  
more complicated.

I have based the above on my assembling Daisy. If there are mistakes  
or if somebody has a better way, fire away!
Good luck
Dave
