How do you fix a popped out jeep fender flare on a 1988?

Pretty easy, there are holes inside and in the back of the flare that match up with holes in the steel fender, mounting hardware is screws from inside the fender to plastic nuts inside the flare, but any nut and bolt that will fit through the hole will work, you may need washers on the flare side though.


What is a flare wrench?

A flare wrench, also known as a flare-nut wrench, tube wrench or line wrench is used for gripping the nuts on the ends of tubes (like automotive brake lines and household plumbing). It is similar to a box-end wrench but, instead of encircling the nut completely, it has a narrow opening just wide enough to allow the wrench to fit over the tube. This allows for maximum contact on plumbing nuts, which are typically softer metals and therefore more prone to damage from open-ended wrenches. See images of flare nut wrenches by searching google and see what purchase links pop up. Cheers

How do you change the steel brake line from the frame to the rubber line that goes to the axle on a 1992 dodge Dakota?

Sound like the main line, front to back. Trace the line up to the front and find a solid place in the line, cut it with a line cutter and get a brake flaring tool. PUT A FLARE NUT on the front section of the line and using aflarein tool flare the end of the line from the front you're going to save. Buy some steel line and run it to the back where the rubber flex hose is. Cut the old line tight to the old flare nut and get a six point socket to fit tightly over the nut. Use a line wrench to keep the flex hose from turning and loosen the old nut. Measure you new line, cut it to fit, take it off the truck and PUT NEW FLARE NUTS ON THE LINE FIRST then flare both ends & install. Bleed the brakes at the wheel cylinders and it should be fine. If you have to replace the whole line its the same proceedure except you remove the flare nut at the front end and then make a longer line. Premade lengths are also available and you use connectors to join them.
