The frustrating thing about having Owners Groups is having an opinion, answer, Idea or a possible solution for a question or problem and having to join a group to express it. If I or any of us have to join every group to express helpful information what point is it to have them? I'm not a fan

OK then, tell it like you see it Rich! LOL. I do agree though, there are many times I have had some input on a question I saw but just did not want to join yet another group.

That is the frustrating thing Pat. The owners group is a good thing for those folks but It comes at a cost to the open forum concept that lead me to this site in the first place. The ability to do that is still there I know but  it's just harder to fish around the O.G.'s . Maybe we should just let it evolve for a while and maybe I can adapt.

I could not agree more.

ill see if you wanna try to help me out.

Any Old timer Mechanics out there

Ok the front axle on this is 3,300 lb rating. All of them that I see for that year are the same size.
Here's the question is the rotor bigger than the normal size or thicker.

If its bigger then is the rotor just stood higher to compensate and using the same mounts.

Well Dave I found somewhere that I could reply. I am guesing you have a Class C Dodge based on the B series van. If so it has an idependent front suspension so no real Axle. If you have a small Class A let me know as they are a solid axle arrangement. There are several things that can change with axle capacity on the b-series Class C. The possibilities are spindle size and bearings which would lead to a different hub and possibly different rotors. Front springs would change with axle capacity. If it is a Class C odds are good you could go with the B200 or B300 depending on your chassis and you should be able to see if there are differences. Dodge was prety good at keeping the differences to a minimum to save costs of manufacturing.You did not mention the year but again Dodge was good at using the same parts as many places as possible. It is possible that your particular year model used the same brakes on all of the B300 chassis. Going up to the Class A units each level of chassis used different front axles and there were different hubs and bearings used.

Thank you for the input.

The van is actually a 1978 F30 sportsman with independent front suspension as you guessed. I have gust looked at the manual online to confirm that it has no actual axle.

The trouble that I have is that the vehicle is 80 miles away And ordering parts for the thing is guess work at best.

It is The F3 in the VIN says that it MB300 then the parts manual for the vehicle gives a different number for the single rear axle with 4 wheels than any other. I will have to find the parts manual again and check on the spindle size etc.

My theory was that they may have had brake failure and increased the size of the disk then change the offset on the caliper to accommodate greater breaking capacity. This being that they standardized everything the following year. Most parts places online have drawn a blank Napa have given me part numbers and I just have to fax my local dealer the list and confirm availability. I still like the old beasts with a little metal in them and not recycled tin.

These are all guesses as I was a Chevy man back in the days of interchanged 283's and X frames.

The single rear axle may mean single wheel rear axle as opposed to the dual wheel on th e1 ton Chassis. There were single rear wheel (non Dually) class c rigs out there and the front and rear parts on those are different than those with the dual. The front hubs are different to accept the offset wheels that fit on the rear.

I have Napa on the hunt at the moment for the correct parts. That should give them something different to do. I got a list of parts from Napa canada online but see your own store. So phoned them up with same parts list 5 hours ago and they are still working on it because i have had one returned call

Every group has it's rules. If I need to ask for advice and I get good advice for free then to me it's worth joining a group to get it. I mean if you compare this to many real painful problems in this world, this problem isn't really up there at the very top.
