    JD7 brake boster needed

    I have a 1996 K2500 (454) with JD7 brakes. I'm having a hard time finding a new Hydraboost Brake boster. Everyone wants to sell me JB8 (10,000 lbs) when I have JD7 (8,000 lbs). Nobody seems to list one for JD7. I'm starting to go cross-eyed looking through all these sites and cross-references...

    Power Steering "weak".

    283,000 That's how many miles were on that pump. Lets see if I can get that .any out of the next one. Pump was the issue. Now I can hold my foot on the brake at low idle and steer with one finger.

    14 Bolt FF brake adjustment and setup questions.

    Are you sure you even have brakes at all in the rear? My rule of thumb is drums are properly adjusted when the weight of your hand against the tread is enough to spin the tire, and it stops before 1 complete rotation. When both sides are properly adjusted, you should have a high pedal. Then...

    Changing the fluid in my 14-bolt.

    So anyway.... back to the topic... Given my historty/experience, is this something I could try? Not dure if there are any specialty tools I'd need. My Diff spreader and yoke puller are for the smaller models.

    If the photo is of the passenger side, then it looks correct to me.

    Changing the fluid in my 14-bolt.

    Full-float yes. I've read that these are easier to rebuild than the others I'm used to. Not sure I am in the mood to tackle it right now though. I'm in the middle of building 2 Jeeps (TJ) and I've already lost 2 weeks on this with nothing else to drive. Started with replacing fuel lines. Then...

    Changing the fluid in my 14-bolt.

    The magnet was doing what a magnet does. But should I be concerned? That's the real question.

    Changing the fluid in my 14-bolt.

    No clue. Not sure which bearings to check. Not sure if I want to try. Never rebuilt a 14-bolt before. I've done D30, D35, D44, 10-bolt and 12-bolt. But I understand these are an entirely different animal. A breed of their own.

    Changing the fluid in my 14-bolt.

    Found this stuck to my magnet (3/8" ratchet for scale). Bearing cage? Normal? Everything looks good. No unusual wear on my ring gear. 4.10's, limited slip. ~290,000 miles. Never changed the fluid in the ~9.5 years I've owned it. Constructive thoughts appreciated.

    Low idle is 650 to 675 in gear.

    Power Steering "weak".

    Pretty sure that's about where it is. Might be my tach is off. I'll hook up to the computer next time it's hot and running at low-idle. Keep in mind it drops when the trnsmission is in a driving gear during parking procedures and not in P/N where the idle would bump up slightly.

    Power Steering "weak".

    No, they're all good. I change them fairly regularly. (LLT from Autozone. I think i'm on my...... fourth(?) full set up ball joint, tie-rod ends, drag-links, etc.) Alignment? I rotate the tires every other oil change and it's just the usual light feathering. Nothing unusual.

    Power Steering "weak".

    Well.... the truck has about 280,000 miles on it. I've had it for the past ~100,000. So extrapolate from there? Assume everything feels normal above 1,000 RPM. Low-idle: Brakes are good Steering is good Steering when foot on brake, not good. Does that sum it up clearly enough? ;) Does that...

    Power Steering "weak".

    So I'm yeah.... Which brake code do I have because I'm not seeing JB... anything on this. JD7 is the answer... but it's not an option anywhere I try to lookup a proper pump. So.....

    Already did that.

    Power Steering "weak".

    Any suggestions where a person could get a decent NEW pump without spending a million bucks?

    Power Steering "weak".

    Thanks for all the responses! No wires on the back of my pump. Just one pressure line and two return lines. The issue happens only when the truck is at low idle. ( 575 RPM ). Fast idle (1500 RPM... yeah.... The thing idles at 35 MPH when cold) has no issues. Even as low as 1,000 RPM I have...

    Power Steering "weak".

    Ok.... #1, I think hydraboost is the dumbest thing ever. It runs off the P/S so if your P/S dies, or you throw a belt, or you have a low idle, you can't steer and you can't stop. At least with vacuum assist you could still stop. Anyway... I've owned this truck for over 9 years and it's like...

    My speedometer is a little off...

    I ordered a new air core motor off eBay. I'll see how it works and update here.

    My speedometer is a little off...

    The ECM/VSS is reading correctly. It's off by 10% inline with my ~33in tires. When I bought the truck 8 years ago, 30 was 35 and 60 was 70. Now 60 is ~80 and 70 is ~100. So really, the only way is a new cluster?

    My speedometer is a little off...

    The tach is a little off too, but I also have 33's. Call it "70ish" but still... Less than 80 and far less than 100. But what can I do to fix this?
  22. mpyusko

    My speedometer is a little off...

    Seriously though... How can I fix this? I was in Ohio doing 70 on the interstate when I took this photo. The VSS is reading correctly.

    Proportional Brake Controller

    So nothing that taps into the brakes anymore? That seems like the perfect proportional control. I'll have to check out the P3 as it seems to be preferred.

    Rear coolant leak

    Except Everytime I go there, they try and sell me a new truck. And when that fails, they try to sell me part that cost almost as much as one.

    What happens at 3500 RPM?

    Ya know I've always said the truck is kinda amazing. "It's like the more power it needs, the more it creates". My example our old minivan was pretty zippy, but when you loaded it up with 8 people, it was a slug. The truck though.... I had a half-cord of firewood, 6 people and camping gear in...
