Title: I hope my frame is not bent
Post by: ray bear on June 17, 2026, 03:48:04 AM

Rebuilt the Koni 7610 dial a ride on my Eldorado only to find they wouldnt go back on without a fight, the shock mount bolts from left to right are 2mm different in spacing , this has never been a problem or I didnt notice with the old worn shocks , I fitted the shocks to find that the axle bolt is now a tight fit so placing stress on the swing arm , I can re adjust the pinion to rectify but that doesnt fix the problem of different mount bolt spacing , mount bolts are straight so is it swing arm or top frame rails that are 2mm out , Im hoping its swing arm as I can replace or try and twist it back to square, if its the top frame rails  I think its beyond me heres hoping .

Loosen 4 nuts on swingarm that hold rear drive. Insert axle then retighten 4 nuts to 23ftlbs. This should help.

Yep, you’re sposed to tighten the axel before the four mount nuts that hold the drive. Are the shocks still the same length?

Thanks for your input guys appreciated  but I know how to align the axle , the frame or swing arm is bent by 2mm and I dont know how to determine which one it is so I think the easiest way might be to look for a good swing arm and replace it and see if that corrects the problem , I do not re align the axle to compensate for a frame misalignment I want to rectify the problem , to wrongs dont make a right

Just some ramblings..
Get a spirit level or two and a plumb line.
Put bike on centre stand and remove the seat.
Before the rear frame rail starts i.e. near to the rear of the tank, place a spirit level across the frame rails.
Shim the centre stand until the bike is level, side to side.
Using a plumb line, measure the height of the mounting points, from the deck/ground.
If the top mounts are different, then it's the rear frame rail(s).
Likewise, if the lower ones are different, then it's the swingarm and/or bevel drive.
