This guy is likely not an English first language guy, so I decided to give him a break. I'm glad someone else notices.

It is correct.. my native language is Spanish... but I do not get it... IFS suspension is a wrong definition of suspension based on not-solid differential like samll cars have??...

ES_97sport.... thansk for your advice... just to be clear.. HP means High Pinion? nothing related with reversal cut?..

Thanks

You have it correct but IFS already stands for Independent Front Suspension. So when you say IFS front suspension you are being redundant. This is because soon as you say IFS people already know it is in the front and the type that it is.

No problem, Jorge. Yes, HP is 'high pinion'. The High Pinion Dana 44 uses a reverse cut gear. The article below explains some of the terminology.

Dana 44 Solid Front Axle

I don't think the XJ ever came with a HP anywhere (not sure ANY Jeep did). I could wrong but HPs are not common in newer 90ish+ vehicles. In the US it was a fairly common Ford pickup/Bronco part in the 1970s-90s.

If finding a HP is problematic where you are a possible solution is to move the t-case back giving you more length to work with for the drive shaft. That bad part is that will drop your drive shaft well below EVERYTHING. <img src="/forums/images/graemlins/frown.gif" alt="" /> There is a fix for that, too, unfortunately it requires a HP.

The two points for installing a HP: keep the DS as high up as possible for clearance and keep your DS angles sane.

An XJ axle isn't going to just bolt in so getting all the brackets with the axle doesn't really buy you anything. My suggestion would be to get a good axle and then get brackets and have them welded on where you need them. There are 3 and 4-link bracket kits available from a dozen companies (at least).

Tag, yea, right up to the point someone starts talking about IFS on the REAR of a vehicle. IFS gets used generically to refer to front or rear a lot. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

Edward and Tag thanks for the explanation of the IFS terminology... as you said it was redundant.. sorry...

Also, thanks for the advice on the Dana 44... I will check the differential today morning.

Jorge

Exactly. the magazine writers, and editors are the worst.

Good info Ed!! I needed some education in HP stuff.

No problem! Yea, no doubt. I was at the dealership not too long ago and heard someone say, 'Yea, and it's got IFS front and rear!' I thought, 'DANG! I gotta get me one of those! A REVERSEABLE CAR!'

Edward

]Edward... another question.. why the front Dana 44 should be HP??... any concerns about angle of the front cardan bar? or there is another implication?

Thanks

There is a few more inches of clearance for the driveshaft with HP. There is nothing wrong with LP. Also, if you going to be lifting it really high especially with a short wheelbase, The LP will give you more driveshaft angle problems and may require a special driveshaft made. HP has less problems with driveshaft angles.

BUT, if LP is what you have, I'd say just use that <img src="/forums/images/graemlins/kewl.gif" alt="" />

For what it's worth, I run a low pinion D44 in my truck. It doesn't seem to care if the pinion is at the top or bottom. <img src="/forums/images/graemlins/smile.gif" alt="" />
