Rear Brake Proportioning Rod & Bump Stops


Recommended Posts

OK well as far as I know my Comanche's suspension is stock (maybe is maybe isn't honestly but it looks stock)... here's the deal, I know the "arm" that the rod connects to is supposed to be horizontal when the truck is unloaded but mine clearly is not.

 

Is there some way to fix this? I know at least one member has made an adjustable rod but that's probably not do-able for me. I would like to keep things bone stock for now.

Are those stops not stock? The rear of the truck rides horribly rough over bumps. Does everything look stock? Maybe a PO monkeyed with stuff, I don't know.

 

You know... I was thinking just last week that maybe my rear shocks are too long and that's why they are so rough... but after looking at the pic I posted you can tell the axle is hitting the bump stops, and there can't be that much room to move... the bump stops do look big. Anyone got a shot of stock bump stops on a stock truck?

 

p.s. Yeah the spare tire hoist is on my "to-do" list.

Skidoo is right . Those are not the correct bumpstops . It's pouring down rain right now or I would send a pic of the correct ones . Instead of them being round like yours they are there supposed to be (for the lack of a better word ) bread loaf looking lol. I would say that it looks like the reason your brake arm is off is because the leaf springs are old and have sagged over the years .

Seems reasonable. Is this what I'm looking for? http://www.amazon.com/gp/product/B000FQ7TMG/

 

Those "bump stops" are Timbrens. They act as overload springs and I have run them on my 91 Eliminator for over fifteen years. I'll buy them if you really want to pitch them. They don't effect the ride unless you are well loaded.

 

OK I'm going to check but if I am hitting those bump stops like I think, I will be removing them.

Edit: Holy cow is this them? http://www.suspensionconnection.com/jfc01-comanche-load-support.html

Yes.

The ones in your link are for the front.

 

If you are consistently hitting those Timbren bump stops in the rear, do NOT remove them. Your springs are shot and the Timbrens are doing a lot of the work in your rear suspension. What you really need is new springs ... then you could think about stock bump stops.

Oh here's the rear link: http://www.suspensionconnection.com/jrc01-comanche-load-support.html

 

Well that sucks that I might be spring shopping...

 

I've got a GoPro so if I can get it rigged up somehow and go for a drive, I'll post the video and you helpful guys can help me figure out why it rides so rough in the rear :-)

Aw crap... I got under the truck with the flash light and both springs are cracked all the way through, broken. 2nd leaf from the bottom in front of the U-bolts on both sides.

 

UGH... I don't mind tinkering on my Jeep but now it's becoming a money pit :mad:

This thing just passed a provincial safety inspection last December, I wonder how it passed...

Can you tell if the springs are shot by looking at them? I could get a better photo if that helps...

No, we can't.

 

If those Timbren bump stops aren't making contact with the axle tube, measure straight up from the top of the axle tube to the underside of the frame rail at the point where the bump stop attaches. Measure both sides. The correct measurement should be 8.2 inches for 2WD or 9.2 inches for 4WD (both plus-or-minus 1/2-inch).

The springs may not have been cracked then. I don't think those aftermarket bump stops did you any favors.

 

Where are you in Canada? I have a couple of sets of MJ leaf springs in the garage. There are some cracked leaves, similar to yours. My plan has been to make two "good" springs from the four busted ones. I also have some Wrangler YJ leaves -- I'll see if I can figure out what might work for you. Do you want to get back to stock height and ride, or do want to lift it some while you're doing it? (Please tell me you want stock height!)

I'm in western Canada.

 

This is funny, I checked the tire pressures on the truck and found the rear tires were at 40 psi and 48 psi (holy #@*&) so I put them down to 32 psi and oddly enough the rear end doesn't ride so rough LOL. I will have to do something about the springs still, but wow, I wonder why the PO had never checked the tire pressures (the fronts were at 31 psi & 40 psi). They are almost new tires from Wal-Mart so I can only assume Wal-Mart set the pressure and since they were new the PO just never checked them.
