98 5 speed manual rolls while parked in gear?

The last 2 times I've parked my truck in a steep driveway and put it in gear it's slowly rolled back several feet before i got back to it. My parking brake is shit so thats not an option what am I looking at? Bad clutch? Bad tranny?

 

What gear was it in? Reverse is the lowest and least likely to move. Unless the clutch is shot (slipping) or the engine is light on compression there is not much you can do to keep it in place if the trans is broken it would be at the bottom of the hill. Fix the parking brake they work great when they are applied.

 

Was it just a ridiculously steep hill? I didn't think it would roll at all in 1st but mine will... and roll relatively fast. I was trying to push start it with absolutely no battery juice... and I mean absolutely none. I popped the clutch in first and it just kinda went put put put as the engine was turning without the fuel pump engaging or injectors or spark plugs firing. I figured the wheels would just lock but it will actually roll. I don't see how it would just roll a little though... Once it breaks the engine loose it should keep going. You sure it isn't physically sliding?

 

Mine does it on a decent inlcine and I have a strong clutch and engine compression, I figure the 35's are just a little heavy for the driveline.

 

I'm positive it's rolling, but only a little at a time. I don't know if i've tried Reverse, but first gear rolls, really slow, like the engine compression is TRYING to hold it back, but then it turns over, a few seconds later, it rolls more, again and again. I suppose I'll try reverse tomorrow. Would a tire shop be able to adjust the parking brake?

 

how steep of a hill is this? sounds big

 

I dunno, they are just driveways. 30-45 degrees?

 

45 is pretty steep. the parking brake adjustment is easy. but if its not the adjustment thats the issue i have no idea. to adjust it you just tighten the nuts under the frame. if you get under and look you will see it. its easy to spot

 

Put it in low range.

 

Ever heard of ring gaps? Pistons and cylinders don't seal 100%....especially under static conditions. It doesn't matter what gear it's in, it will leak down and your truck will move on any kind of a hill. Fix your parking brake or carry some wheel chocks?

 

manual trans means you need a functioning parking brake on steep hills. Low range might work.

 

You shouldn't ever need to adjust the nuts on the cables. Adjust the shoes themselves. If the drum and shoes aren't worn out and the shoes are adjusted properly, the brake should work fine. Properly adjusted, you should get about 4 or 5 clicks on the handle before you can't pull it up anymore

 

FSM says 12-18 clicks.

 

Crap, I was thinking 4 runner with a lever, not a pull handle....handle should move about 3 inches

 

Thanks guys, I'll look into the drum adjustment, just seems like this was never an issue before...

 

Adjust the rear brakes first then adjust the cable if it needs it. The type 1's were famous for the pivot rusting up where the cable attaches to the lever on the backing plate then the parking brake would not release some thing to check after you get the brake working.

 

45 degrees? LOL Bristol Motor Speedway has a 38 degree bank that will nearly roll a car if it comes to a stop on the high side... hehehe Driveways are more like 5-10 degrees, maybe 15-20 in the mountains...

Yes, any tire/brake shop should be able to adjust it.

 

lots of driveways around here are around 30 degrees. One of my neighbors driveways was probably 40-45 degrees before they dug it out and added another whole story to their house underneath what used to be ground level. It's still probably 15-20 degrees now.

 

What the.... Anyone know if this would work? haha sounds easier than jacking it up, removing the wheel, tearing the drum apart, adjusting, putting it all back together...

There are some steep ass driveways here, my sons daycare lady has one and my buddy has one, maybe not 45 degrees but very significant. I'll check with a protractor if i can remember to bring one home from work

 

your truck shouldnt start to roll and just keep going unless your trying to push start it and get enough momentum then take off the clutch.

it will roll a little bit at a time, you can try this V V

maybe you just didnt notice it?
