So as part of my project bike I needed to fit a new steering rod bearing. The out ring of the bearing wasn't going to be removed without a struggle (that's a story for a different time) so I had to remove the wheels, the front brake assembly, suspension trusses, shock, drive shaft and front diff to be able to get at the bearing.
Any way I have come to put it back together (lost the photos that I took beforehand) and something isn't right. The rims of the wheels are just touching the shocks in a straight line, when you turn the steering the wheels are hitting the shock.

I've tried to the take photos as best that I can.
Anybody care to suggest what is wrong? Have I put something on the wrong side, back to front, upside down?
Any suggestions gratefully received!

FWIW here’s a pic of my 93

Is it just the right side?

I’d have to wonder if the lower and or upper A arms were swapped. compare lower knuckle tab positions. Are you using the manual?

Your lower right A Arm has a roached crossmember—is it bent?

The more closely i looked, the more i thot it was a good assembly.

Also suspect the wheels—maybe they are off another rig—wrong offset?

The lower right A arm badly corroded tho

Yeah, sorry. That was my original quad. Must update my signature.

I think those are the wrong offset wheels, and that's the problem that's causing them to hit.
Well I never!
The front wheels are similar condition as the struts and the front of the frame (i.e. rotten) so it didn't cross my mind that the wheels might have been swapped at some point.

Looking at the Rear Wheel, looks like that might be off a different model as well?

Wow those wheels are about gone!

The rear offset is supposed to be different than the front offset on a 300. Those look like original wheels, but odd that they would sit so close to the upper a-arm.

Don't you have another 300? Swap the wheels, see if the fitment is the same.

My main 300 is several miles away so it won't be easy to swap them around. I've attached a pic of my main 300 and the wheels do look different.

The only thing that is making me question it, is that the condition of the front wheels just kinda looks right in comparison with the rest of the front end.

yep agreed - those are trx 350 rims.

years ago I had a guy drop his 300 off because his front end "needed work"

well, he had 350 front rims on his 300 FW. the rims wore clear through the bottom eyelits of the shocks!
yeah...the off-set on those old school trx350's are wayyyyyyyy different than any trx300 front rims !..lol. I noticed this years ago..very strange to say the least, but thats how honda made those rims back then for those old girls :).

Thanks all for the replies. Greatly appreciated.

Looking at this ad for a similar aged (i.e. 1999 / 2000 ish) TRX300, they have similar wheels to the ones that I have -

https://www.ebay.co.uk/itm/HONDA-TRX-300-FourTrax-1994-2000-not-sure-of-age/303118031703?hash=item46933e1b57:g:tmYAAOSwxAxcp3O2

Did the last of the TRX300's ever come with the same wheels as the first TRX350?

I'm assuming that they must be using spacers in order to stop the rims hitting the shocks?
no, honda never used the rim sizes from the old trx350's on any of their trx300's.

Here’s a pic of a 90s trx300 with similar rims.

Ok i took some measurements from what i can tell there should be 1 1/2 inches of clearance betw tire sidewall and shock eye

The offset I measured on a trx300 wheel is 5 inches; tire width is 8 inches

the offset on a trx350 wheel is 8 inches; tire width is nine inches.

If you measure your wheel depth then you know
