Doug, Paul or Michael Tzetlin, Designer, Minirestorer or whoever you are,
You have to be honest with the work that is involved in refurbishing a subframe. If I added up my time using hand and machine tools, I would figure for a rear subframe, and this is what I would pass onto you. Workshops are not a charity, and nor do they operate in 5 minute increments. If it takes 22 minutes, then it takes 1/2 an hour.
So:
Subframe, Remove from car: 1
Radius Arms, Remove: 0.5 hour
Radius arm bush and needle rollers, remove(both): 1
Radius arm bush and needle rollers, replace(both): 0.5
Radius arm bush and needle rollers, hand ream(both): 2
Subframe blast: 1
Subframe Prep, Prime, Paint: 1
Brake Lines, Remove, Fabricate: 1
Slave Cylinders, Remove, refurbish and reinstall: 1.5
Brake Limiting Valve, Remove, Refurbish:1
Brake Pads, Replace 0.5
Wheel Bearings, Remove, refurbish and replace(both): 1
Drums, Remove, machine, replace: 1.5
Rebuild subframe: 2
Reinstall, align refurbished subframe: 1.5
So I get 15.5 on just the rear alone. If I was to consider a job in my home or work workshops.
I will have missed a stack of things, and presumed that the parts don't need to go to a machine shop to be machined, so there will be a stack of things I haven't managed to account for. I'm not going to make the numbers up however to make the difference. I'm just saying there's things I can't account for.... So no offence to the business owners out there who might deal with greater numbers than these to repair a rear subframe.
I reckon the numbers are fair, particularly for a small workshop environment where the room needs to be created and the scale of economies can't be utilised as if you did one subframe after the other infinitum. If you've never reamed rear arm bushes, you probably don't know how difficult this can be for time. I've been generous there as I usually take 2.5 to 3 hours to ream, as I am careful, but not the slickest at the job and don't do it often enough to do it quickly.
